Electronic Delay Fuse Technology For Single Soldier Intercepting LSS-UAV Ammunition

The low altitude?slow speed?small unmanned aerial vehicles(LSS-UAV in abbreviate)because of its easy manipulation,reflecting off suddenly,small cross-section,concealment characteristics,make it become the difficulty and focus of city air defense.Individual found low slow small aircraft and intercept,should not use the existing air defense weapons and firearms,need to choose low collateral damage.The electronic fuze delay is the key part of ammunition can accurately intercept the LSS-UAV to implement,the conventional resolving operation in large computer systems,complicated structure,inconvenient to carry,therefore,need to study a simple structure the miniaturization of trajectory calculation device,which is applied to individual intercept LSS-UAV of the fuze setting system.This paper through a large number of literatures,the research model and numerical solution of the projectile motion,the external ballistic equations are combined with iterative algorithm,the reasonable design in advance,quick and accurate position to intercept ballistic LSS-UAV solution method;design overall scheme to intercept electronic Ammunition Fuze delay system and using STM32F407 and STC89C52 RC microcontroller as the core device,the design of trajectory calculation device and fuze receiving device through wireless transmission system;ballistic solver and fuze receiver communication,fuze receiver work through the received information memory is read to determine the delay time,set up the hardware circuit;finally and the function of the system is verified.In this paper,based on the theory of the original electronic time delay fuze,the improved design of the ballistic solver is completed,which has a certain application value for the individual interceptor LSS-UAV.
