Detection Probability of Four-quadrant Circumferential Laser Fuze of Anti-aircraft Rocket Projectile for Swarm Unmanned Aerial Vehicle

The rendezvous model of the anti-aircraft rocket projectile and the incoming swarm unmanned aerial vehicle (UAV) is described by using the method of spatial analytic geometry. A scheme of a four-quadrant circumferential laser fuze for anti-aircraft rocket projectiles is proposed to detect the incoming swarm UAV, and a detection probability model of projectile-target rendezvous based on Monte Carlo method is established to improve the detection probability of laser proximity fuze of anti-aircraft rocket projectile for the incoming swarm of UAV. The detection probability of the system under the conditions of different rocket projectile and target speeds，laser pulse frequency and detection radius is analyzed.The calculated results show that the probability of the system effectively detecting a target within 8 m is 0.788 8 when the laser pulse frequency is 55 kHz and the rocket projectile rotation speed is 40 r/s.The Monte Carlo calculation model of the system detection probability can provide the theoretical reference for the design of four-quadrant circumferential laser fuze system of air defense rocket projectile.
