Research On The Four-quadrant Peripheral Vision Laser Fuze And Warhead Of Anti-UAV Rocket

This paper mainly studies the cooperation of the four-quadrant peripheral laser proximity fuze used for Anti-UAV rockets and the directional warhead.Relying on XX mm air defense and anti-missile rocket weapon system development project,the "Harop" UAV is used as the research object.To study the coordination law of the fuse and warfare system of air defense rockets,and to provide a theoretical basis for improving the efficiency of the fuse and warfare coordination of Anti-UAV rockets.This paper proposes a four-quadrant peripheral vision laser fuze scheme,which includes the equivalent model of "Harop" UAV,four quadrant laser detection model,detection probability calculation model of missile target intersection based on Monte Carlo method,warhead fragment dispersion model,single fragment breakdown damage probability model,the best initiation delay and the best initiation azimuth calculation model.Based on the mathematical model used to analyze fuze warhead coordination,statistical analysis are carried out by using Monte Carlo method,and the detection probability of four quadrant perimeter looking laser fuze is simulated and analyzed by using MATLAB.The main factors of laser pulse firing frequency,projectile rotation speed,detection radius and target speed are obtained to influence the detection probability of the four-quadrant peripheral laser fuze;Based on the simple evaluation method of fragment warhead damage target,the relationship between damage probability of air defense rocket to UAV target and projectile speed,target speed and missile target distance is analyzed,and the relationship between warhead parameters and damage probability is analyzed.Under the condition that the target is simplified,the models of the optimal initiation delay and initiation azimuth angle are established.Based on this model,the relationships between the optimal initiation delay and initiation azimuth angle and the initial azimuth of the target,the static dispersion velocity of fragments and the distance between the missile and the target are simulated and analyzed.According to the fuze warfare coordination efficiency index,the design requirements for the fuze and warhead related performance parameters of this Anti-UAV rocket are put forward.
