The working principle of the invention is introduced as follows:
as shown in fig. 6, when a protected target (such as a ship) is irradiated by a target indicator of a semi-active laser guided weapon of an enemy, a laser alarm near the protected target recognizes laser threat signal original code information of enemy indicating laser, the laser alarm gives an alarm, and an unmanned aerial vehicle 10 carries a laser optical fiber false target (i.e. an optical fiber outlet collimator 9 and a laser optical cable 6) to ascend; the laser information processor 3 copies laser interference signals similar to or identical to the original code information of the laser threat signals, controls the laser jammer 4 to output the laser interference signals, then transmits the laser interference signals to an unmanned aerial vehicle-mounted optical cable terminal (an optical fiber outlet collimator 9) through a laser optical cable 6 to output the interference signals, and forms a large interference airspace in the weapon attack direction. Because the light intensity of the laser interference signal is higher than the light intensity of the laser reflected by the real target, the weapon seeker selects the direction of the optical fiber laser false target as an adjustment error control signal, and guides the optical fiber laser false target to achieve the aim of angle deception, and the induced bias effect is as shown in fig. 6.
When the laser interference device responds, the laser fiber bait is lifted to be in place, and at the moment, a laser interference signal is transmitted to the optical cable terminal through the laser optical cable 6 and irradiates the direction of the seeker of the semi-active laser guided weapon through the optical fiber outlet collimator 9. The weapon has two targets, namely a real target and a laser fiber bait, in the field of view, the light intensity of the bait is greater than that of the real target, and the weapon deviates towards the mass center of the two targets. In the weapon deviation process, the unmanned aerial vehicle 10 can continue maneuvering and keep away from the real target, and meanwhile, the bait interference airspace is reduced by adjusting the focal length of the laser optical fiber bait, so that the weapon is guided to finally follow the bait direction and deviate from the real target, and therefore the purpose of deviation guiding is achieved, and the safety of the real target is protected.
The optical fiber bait is suitable for targets in motion, such as ships, tanks, war chariot and the like, and is also suitable for targets to be fixed (when diffuse reflection plates cannot be laid).
