Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is a sensing compound anti-armor projectile that investigates and detects a target from above the target, and fires a self-forging projectile from an appropriate altitude to destroy the armored weapon. Regarding.

(Conventional technology) Missiles and guided artillery shells are used to destroy long-range armored weapons (fli vehicles, armored vehicles, self-propelled artillery, etc.) that are out of line of sight, but their speed is slow, so armor-piercing bullets are used in the warhead. cannot be used,
All use high-explosive anti-tank shells (hereinafter referred to as HEAT).

However, modern armored vehicles use composite armor that includes heat-resistant ceramics, making it difficult to penetrate with HEAT. Additionally, the armor on the front and sides of a tank is thicker than the top, making it difficult to penetrate.

Several self-forging bomblets released near the target by the carrier bullet (parent bullet) form and eject an armor-piercing object that is faster than the armor-piercing bullet of a tank gun, so it is difficult to determine whether the bullet is still fast or a slow mortar attack. cannon,
It can be fired from high-explosive shells, rocket launchers, etc., and since it does not depend on the speed of the ammunition being carried, long-distance shooting is also possible.

Therefore, a submunition is released roughly above the target using a carrier bomb, and by descending slowly with a parachute and tilting at an angle of approximately 30", a circle with a radius of 172" at an altitude is searched, and the target that falls within the circle is destroyed. A method is being considered.

(Problem to be Solved by the Invention) In many cases, either millimeter waves or infrared rays are used alone in sensors for missile target detection using this method.In this case, infrared rays are used to detect clouds, smoke, Detection becomes difficult if the target is blocked by fog and has taken measures to reduce heat generation. On the other hand, millimeter waves have a weakness in that they become difficult to detect if the target is disguised or equipped with radio wave absorbers.

Furthermore, in this system, the higher the altitude at which the self-forged bullet is ejected, the larger the scanning range will be, and the higher the target acquisition rate, but the lower the probability of hitting the target. The opposite is true if the ejection altitude is small.

The present invention has been proposed in view of the above points, and its purpose is to be able to fire from mortars, field artillery, and rocket launchers, and to investigate the enemy's area from above the target area. The objective is to provide a sensing complex anti-armor bullet that reliably detects a target using a combination of millimeter wave and infrared detection devices, and fires a self-forging bullet capable of penetrating armor from above at an appropriate altitude using a radio range finder.

(Means for Solving the Problems) In order to achieve the above object, the present invention emits millimeter waves during spiral scanning during the descent process, and detects the presence and altitude of a target object. A detection device, an infrared detection device that detects and identifies infrared rays radiated by the target during the descent process, and a micro-armored bullet that penetrates armor through explosives through detection by this infrared detection device and the millimeter wave detection device. This is an anti-armor bullet that includes a self-forged bullet.

(Function) The present invention uses a radio distance meter to perform spiral scanning at a moderate altitude, balances target capture rate with hit probability, and detects targets by coexisting millimeter waves and infrared rays. The accuracy has been improved.

(Example) Hereinafter, the present invention will be explained along with the drawings.

FIG. 1 shows the configuration of a sensing compound anti-armor bullet according to an embodiment of the present invention, in which a self-forging warhead 2 is provided at the front part of a substantially cylindrical structure 1a, and inside the is equipped with 3 explosive charges. Note that the self-forging warhead 2 is a bullet that is formed into a slightly armored bullet shape by the explosive charge 3 behind it, and is capable of penetrating armor at high speed.

Further, a fuse 4 for igniting the explosive charge 3 is provided inside the structure 1a, and a window is opened in a part of the structure 1a, and a proximal end is provided outside the structure 1a. is pivoted to the body structure 1a side, and an infrared reflecting mirror 5 made of mirror-finished stainless steel is attached, the tip of which is directed diagonally forward and can be expanded at a predetermined angle. Therefore, within the structure 1a, there is an infrared sensor 6 that functions as an infrared detection device that detects and identifies infrared rays radiated by the target, and a millimeter wave is emitted during the spiral scanning during the descent process to detect the presence of the target. A seeker-less radio range meter 7 is provided which detects the distance and altitude and functions as a millimeter wave detection device.

The front part of the structure 1a houses a flat plate antenna 8 for seeker-free radio distance, and the rear part houses a parachute 9, which is a combined sensing anti-armor type that uses both infrared and millimeter waves as sensing means. It consists of bullets.

FIG. 2 shows an artillery shell 10 equipped with a plurality of sensing compound anti-armor bullets having the above-mentioned configuration. A warhead 11 having a timer is provided.

In operation, the warhead 11 of the fired shell 10 explodes at a preset time, and the plurality of sensing compound anti-armor shells are each scattered into the air.

Then, as shown in Figure 3, the parachute 9 opens,
The sensing compound anti-armor projectile descends while floating in the air, and the parachute 9 may be replaced by a rotating blade.

In this case, each sensing compound anti-armor bullet is tilted obliquely to the rotation center axis 12, and falls while scanning the optical axis 13 of the infrared sensor and the radiation pattern center axis 14 approximately parallel thereto in a spiral pattern. 15 in FIG. 0 is a spiral locus drawn on the ground by an extension of the radiation pattern center axis 14 of the seeker-radio range finder 7, which is substantially parallel to the optical axis 13.

When the built-in radio distance meter 7 detects the effective firing range to the ground G, the combined sensing anti-armor bullet enters the arming state and descends while tracing a trajectory 15 on the ground G.

When an armored vehicle or the like exists on this trajectory 15, the optical axis 13 of the infrared reflecting mirror 5 provided on the sensing compound anti-armor bullet and the radiation pattern center axis 14 of the flat plate antenna 8 will hit the armored vehicle or the like. An infrared sensor 6 detects the infrared rays radiated by the vehicle, and a seeker detects radio waves reflected by hitting an armored vehicle or the like, thereby igniting the fuse 4 and detonating it. Then, the self-forging warhead 8 flies at high speed toward the armored vehicle or the like in the bullet axis direction while being forged into a slightly armored bullet shape and destroys the armored vehicle or the like.

As described above, in the present invention, even if the target takes measures to suppress heat generation, the presence of the target can be detected by the seeker, and even if the target takes measures to absorb radio waves, the presence of the target can be detected even if measures are taken to suppress heat generation. If not, it can be detected by infrared sensors and targets can be detected and destroyed with high precision.

(Effects of the Invention) As described above, according to the present invention, there is provided a millimeter wave detection device that emits millimeter waves and detects the presence and altitude of a target while performing a spiral scan during the descent process; an infrared detection device that detects and identifies infrared rays radiated by the target object during the process;
This infrared detection device.

A self-forging bullet that is forged into a slightly armored bullet shape that penetrates armor through explosives when detected by the millimeter wave detection device, and the effective range altitude is detected by the millimeter wave detection device, and the position of the target is detected by the millimeter wave detection device. Detection is done using reflected millimeter waves and infrared rays radiated by the target, resulting in highly accurate target detection and effective target aiming.
