Decoying effect evaluation system of laser decoy jamming equipment based on unmanned aerial vehicle formation

Abstract

The invention discloses a decoying effect evaluation system of laser decoy jamming equipment based on unmanned aerial vehicle formation. The system comprises a first flight device, a first image acquisition unit, a first image tracking processing unit, a laser target indicator , a second flight device and a detector in the second flight device, wherein the first image acquisition unit, the first image tracking processing unit, and the laser target indicator are arranged in the first flight device. During flight, the second flight device is arranged at a set distance near the first flight device, the relative position of the second flight device and the first flight device is kept unchanged, and the posture is kept consistent with that of the first flight device; the first image tracking processing unit calculates the position of the target according to the image; and the laser target indicator emits laser to the target. Before and after a to-be-evaluated laser decoy jamming equipment arranged on the target is started, laser reflection signals detected by the detector are calculated respectively; and the decoying effect of the laser decoy jamming equipment is evaluated according tothe deviation of the positions calculated before and after. According to the system, the decoying effect of the laser decoy jamming equipment can be effectively evaluated.

Description

technical field [0001] The invention relates to the field of laser guidance, in particular to a laser decoy jamming device decoy effect evaluation system based on unmanned aerial vehicle formation. Background technique [0002] Laser semi-active homing guidance is the most commonly used laser guidance method at present. Its basic principle is that the laser beam emitted by the external laser target indicator irradiates the target, and the laser seeker on the missile receives the echo signal diffusely reflected by the target to make the guidance system Form the tracking of the target and the control signal to the missile, so that the missile can be accurately directed to the target. According to the attack mode of the laser semi-active guided weapon, it can be divided into the original shooting, the original shooting and the ground shooting. The laser decoy jamming device is an effective device against laser semi-active homing guided weapons. [0003] At present, the decoy e...

Problems solved by technology

However, the ground test method ignores the maneuvering process of the projectile and the target, and the fidelity is not enough; and because the seeker and the target indicator are both erected on the ground, the field of view is limited and cannot effectively cover all the preset areas of false targets. There is a blind spot in the evaluation of the decoy effect of laser decoy jamming equipment
