Description

Functional level simulation method for Tacan system
Technical Field
The invention relates to the technical field of simulation of a Takang system, in particular to a functional level simulation method of the Takang system.
Background
In the early days, two or more ground navigation stations were used for determining the position of the airplane in the air navigation, and the positioning precision was low, so that the positioning technology has no great practical value. Thus, in the middle of the twentieth century, in order to achieve accurate aerial positioning navigation, a tacan system was developed by the U.S. fisher telecommunications laboratory according to the recommendations of the united states air force and navy. TACAN, a well-known name, is a short-range radio navigation system, and the TACAN navigation system is the first short-range radio navigation system in the world capable of simultaneously providing distance information and azimuth information for an airplane. In the 50's of the 20 th century, the navigation system was first applied to shipboard aircraft navigation of a U.S. military aircraft carrier, and was also important equipment for an aerial refueling task completed by an aerial tanker, and was later developed into a standard military short-range navigation system of each member country of the north atlantic organization. The Takang system is one of the important navigation systems of the air force of China, and can ensure that the airplane flies to a target and the air of a airplane group to gather and converge along a preset air route and guide the airplane to home and land on the approach under the complex meteorological condition.
The existing simulation of the functional level of the tacan system is complex, time and labor are wasted, errors are easy to occur in the simulation process, and the tacan system cannot be simulated quickly and accurately, so that a tacan system functional level simulation method is urgently needed to solve the problems.
