1) Bullet damage effect judgment model and software:
taking an air-defense missile as an example, a radio proximity fuse and a trigger fuse are generally arranged on the missile, and under the condition that each device on the missile works normally, the radio proximity fuse is always started in preference to the trigger fuse, so that the damage effect on the target can be comprehensively formed according to the detection starting distance, the detection angle, the fighter part killing radius, the projectile body posture, the fuse geodesic/sea surface height information and the like of the fuse, and the real-time performance of the damage effect judgment is better through multiple ground verification tests and live-bullet target test tests.
2) Specially-manufactured Beidou terminal user machine:
considering that space and power supply capacity on the projectile are limited, the structure adopts a miniaturized design, the antenna adopts a conformal design with the projectile body, two transmitting antennas are arranged on the side wall of the projectile body in two directions of 180 degrees, and the damage effect is transmitted to the star through Beidou short messages.
3) Beidou short message system:
and 5 static orbit satellites and 30 non-static orbit satellites at the space end built in recent years are utilized to send encrypted Beidou short messages containing the damage effect to the covered ground/sea surface receiving terminals.

The embodiment is realized through the following processes:
a) When the missile flies to a certain distance from a target, starting up the missile-borne radio fuze, and continuously detecting the target in the direction of the beam of the fuze antenna;
b) When the radio fuze detects a target, determining the delay time (millisecond level) of a warhead detonation signal according to the measured bullet-target relative distance and the intersection gesture, and simultaneously transmitting a damage effect in the form of Beidou short messages through a bullet antenna; meanwhile, the height measurement signal on the bullet monitors the ground/sea surface height in real time, if the measured height information is smaller than or equal to the distance information measured by the fuze, the damage effect information is not output, so that the false judgment signal of the damage effect is prevented from being made due to the ground/sea surface signal measured by the fuze;
c) When the radio fuze does not detect the target, a message of the damage effect is not sent;
d) The ground/warship surface receiving end analyzes the received Beidou short message in time (the transmission delay of the short message communication function is about 0.5s, the communication frequency can reach 1 Hz), and transmits the Beidou short message to the weapon system fire control unit to assist an operator to make a decision;
e) If the weapon system fire control unit still does not receive the damage effect message after encountering for a certain time (second level) beyond the target theory, the missile is judged to be not hit.
