The basic principle of the guidance is that a laser beam emitted by a laser target indicator outside a missile irradiates a target, and the laser target finder on the missile receives an echo signal of diffuse reflection of the target to enable a guidance system to form a tracking signal for the target and a control signal for a missile, so that the missile is accurately guided to the target. The laser decoy jamming device is an effective device for fighting laser semi-actively seeking guided weapons.
At present, the method for evaluating the trapping effect of the laser trapping interference equipment in the outfield environment mainly comprises a live ammunition target practice method, a full-process simulation method, a semi-physical simulation method, a ground dynamic simulation test method and the like.
