Referring to Fig. 1, Fig. 1 is the flow diagram that a kind of communication link provided in an embodiment of the present invention determines method, application In the first communication ends, include the following steps:
S101 receives the signal of communication that the second communication ends are sent.
Wherein, above-mentioned first communication ends can be earth station, LEO (Low-orbit satellite system, low rail Road) satellite or Medium-Earth Orbit MEO (Medium Earth Orbit, Medium-Earth Orbit) satellite, above-mentioned second communication station can be with For earth station, LEO satellite or MEO satellite.
Shown in Figure 2, the GEO satellite backbone network in Fig. 2 is the network communicated with MEO satellite, LEO satellite star Seat group is the constellation group being made of multiple LEO satellites;And in the satellite communication system in the embodiment of the present invention include earth station, LEO satellite and MEO satellite, therefore communication in satellite communication system between the two is total is related to following several situations:
Situation one: when earth station sends data to LEO satellite, then the first communication ends are LEO satellite, and the second communication ends are Earth station;
Situation two: when LEO satellite ground station sends data, then the first communication ends are earth station, and the second communication ends are LEO satellite;
Situation three: when LEO satellite sends data to MEO satellite, then the first communication ends are MEO satellite, the second communication ends For LEO satellite;
Situation four: when MEO satellite sends data to LEO satellite, then the first communication ends are LEO satellite, the second communication ends For MEO satellite.
After first communication ends receive the above-mentioned signal of communication of the second communication ends transmission, illustrate the second communication ends in the presence of with the The demand of one communication ends communication, and the first communication ends are to guarantee being communicated with the second communication ends for high quality, need to carry out chain Road selection, determines the link communicated with the second communication ends.
S102, obtain second communication ends send used link data when the signal of communication, signal data and First motion profile.
Wherein, from above-mentioned to signal intelligence existing between the first communication ends and the second communication ends description as can be seen that the LEO satellite is certainly existed in one communication ends and the second communication ends, on this basis, above-mentioned first motion profile are as follows: described first It is the motion profile of one end of LEO satellite in communication ends and the second communication ends, the signal data includes: that laser beam is directed toward.
Wherein, laser beam is oriented to the direction of laser transmitting laser beam.
In one embodiment of the present of invention, above-mentioned link data can be with are as follows: leads between the second communication ends and the first communication ends The business datum of communication service or second communication ends send the channel data of the used channel of the signal of communication.
In one embodiment, in the case where above situation one and situation two occur, above-mentioned link data can be channel Data;

In one embodiment of the present of invention, above-mentioned channel data may include: atmospheric visibility and rainfall intensity;
Or/and
The signal data may include: optical maser wavelength, laser beam direction, microwave frequency, launching elevation, polarization the elevation angle and Signal reception power.
Wherein, launching elevation is the launch angle of microwave rf generator;
Polarizing, the elevation angle is related with satellite antenna polarization mode, and when antenna is horizontal polarization, the polarization elevation angle is 0 °;Work as antenna When being vertical polarization, the polarization elevation angle is 90 °;When antenna is circular polarisation, the polarization elevation angle is 45 °.
Since atmospheric visibility and rainfall intensity can directly characterize the variation of atmosphere, and the variation of atmosphere is to laser chain The bit error rate on road can affect, when using laser link communication, when atmospheric visibility and rainfall intensity are in a certain value range When interior, laser link may become difficult capture, the tracking of signal of communication, even result in communication failure.Therefore in determination When communication link, channel data can be used to determine whether that transmission signal of communication can be carried out using laser link.
Signal data can determine when carrying out transmission signal of communication using laser link or microwave link, the laser link Whether signal of communication can be transmitted with microwave link, therefore when determining communication link, need using signal data come Determine whether that the communication information can be transmitted.
S103, judges whether first motion profile meets following relationship:
First motion profile is in the range of the laser beam is directed toward or first motion profile is preset In satellite coverage;S102 is executed if it has not, returning;If it is, executing S105;
Wherein, satellite coverage can be understood as the range that can be communicated by microwave link, and satellite covers model The range can be directly acquired by enclosing.
Microwave refers to that frequency is the electromagnetic wave of 300MHz~300GHz, is the abbreviation of a limited frequency band in radio wave, That is electromagnetic wave of the wavelength between 1 millimeter~1 meter, is the general designation of decimetric wave, centimeter wave, millimeter wave, submillimeter wave.
Microwave frequency is higher than general radio wave frequency, also commonly referred to as " uhf electromagnetic wave ".Microwave is as a kind of Electromagnetic wave also has duality principle.The fundamental property of microwave typically appears as penetrating, reflects, absorbs three characteristics.
The motion profile of above-mentioned LEO satellite is fallen in the range of laser beam direction, it is believed that laser link can be used It is communicated in the second communication ends;
The motion profile of above-mentioned LEO satellite is fallen in satellite coverage, it is believed that microwave link can be used for and the Two communication ends are communicated.
The link data and the signal data are input to link and determined in model by S104, are determined and described second The link that communication ends are communicated;Wherein, the link determines model are as follows: uses sample link data and sample signal number in advance According to mould being trained to supporting vector machine model, for determining communication link in laser link and microwave link Type.
Above-mentioned first motion profile meets above-mentioned relation formula, illustrates at least a kind of link in laser link and microwave link It can be used for being communicated with the second communication ends, need further progress link selection thus, determine eventually for second The link that communication ends are communicated.
Since laser communication can provide the communication service of high-speed, and the traffic rate that microwave communication provides is relatively low. Therefore, laser link can be used in actual use as principal communication link, and microwave link is as the standby of laser link Part link, enables backup link when principal communication link not can guarantee primary demand or communication disruption, to guarantee communication link Reliability.

Wherein, above-mentioned preset format can be following format: [channel data] [atmospheric visibility]: [microwave frequency] [hair Penetrate the elevation angle]: [the polarization elevation angle]: [optical maser wavelength] [laser beam direction].
The above-mentioned corresponding sample signal data of each sample link data constitute a target data according to budget presentation As training points.
Step C obtains multiple kernel functions of supporting vector machine model.
Above-mentioned multiple kernel functions can be the kernel function of user preset selection.
Kernel function may include: the functions such as linear kernel function, Polynomial kernel function, gaussian kernel function.
Wherein, gaussian kernel function is also referred to as radial basis function (Radial Basis Function, abbreviation RBF), and RBF can It is certain radially symmetrical scalar function to map the data into Infinite-dimensional.
For supporting vector machine model, kernel function is different, it may be considered that model is different.In addition, different core The characteristic that function is showed in application process is not also identical.In the case where the sample data for being trained is certain, it is It obtains accurate link and determines model, model training is carried out using multiple kernel functions in the embodiment of the present invention, with training The link being mutually applicable in application scenarios corresponding to above-mentioned sample data out determines model.
Step D obtains the model parameter of the corresponding supporting vector machine model of each kernel function using self-service mode.
Each kernel function that this step obtains step C, using self-service mode to sample link data and sample signal number According to being trained and evaluation test, obtain that each kernel function is corresponding to be still used to characterize use for characterizing using microwave link The classification results of laser link.
Wherein, above-mentioned model parameter may include: penalty parameter c and g parameter.
Parameter c characterizes the tolerance to error.
Parameter g are as follows: the parameter coefficient of kernel function.
Parameter c and parameter g can determine hyperplane, for biggish c value, if hyperplane can be preferably by all instructions Practice the classification results that point carries out test acquisition with each training points correctly to classify one by one, then optimizing will select back gauge lesser super Plane.On the contrary, will lead to the separating hyperplance that optimizer finds bigger back gauge for very small c value, even if the hyperplane is wrong The more points of misclassification.
Parameter g is bigger, and the supporting vector quantity in supporting vector machine model is fewer, and parameter g value is smaller, support vector machines mould Supporting vector quantity in type is more.The number of supporting vector influences the speed of training with prediction.
For example, using self-service mode sample data is trained and evaluation test.Self-service mode can be according to such as Lower three steps obtain optimal parameter c and g:
The first step selects one from sample data set D every time using the target data of preset format as sample data set D Group sample data, this group of sample data is put into training set D1, then this group of sample data is returned in D, so repeatedly For after m times, it will obtain the new data set D1 comprising m sample;
Second step, using D1 as training set, D D1 as test set, supporting vector machine model is trained and is assessed;
Wherein, D D1 indicate data set in addition to D in D1.
Third step, finding makes to assess performance best that group of training set and test set, obtains optimal parameter c and g.
Wherein, above-mentioned assessment performance preferably can be understood as test result accuracy rate highest.
The optimal supporting vector machine model of model parameter is determined as the initial model that the link determines model by step E.
Based on the above-mentioned description to step D, optimal model parameter is determined from determining model parameter.
Optimum model parameter is parameter corresponding to distance maximum of the hyperplane to two class boundaries.
Step F is trained the initial model using the target data, obtains in laser link and micro- The model of communication link is determined in wave link.
In the corresponding sample data of each training points of acquisition, the data for including based on each training points can be obtained together When being communicated, using laser link or microwave link, as the corresponding labeled data of each training points.
Using above-mentioned target data initial model is trained when, it is possible to understand that are as follows: using above-mentioned target data as It is true to obtain the link that above-mentioned initial model carries out link selection based on above-mentioned target data and exports for the input parameter of initial model Determine result.Then the labeled data of training points corresponding to the result and target data of initial model output is compared, and root The model parameter of above-mentioned initial model is adjusted according to comparing result, so that the output result of above-mentioned initial model is right to target data institute The labeled data of training points is answered to draw close, and then implementation model training.
It can be seen that this implementation is used by sample link data and sample signal data using multiple kernel functions Self-service mode determines optimal model parameter, and uses the target data, is trained, is used to the initial model In the model for determining communication link in laser link and microwave link.The link determines model using sample link data and sample This signal data determines optimal model parameter in the way of self-service from multiple kernel functions, so that the link determined determines Model structure is simple, accuracy rate is high, so that the link after the training determines that model can be determined according to Changes in weather in real time Optimal communication link out, to improve communication efficiency.
