Study on Determination of Fire Conflict Between HPMW and Vertical Launch Weapon in Cooperative Operation

Abstract

The naval application of high power microwave(HPM)has become an inevitable trend in the development of future naval weapons. In order to maximize the operational advantages of high power microwave weapon(HPMW)in cooperative air-defense operations,it is important to study its cooperative operational fire-conflict and its determination method. Aming at the problem of the fire conflict between HPMW and vertical launch weapons,the launch characteristics of HPM was considered as well as the mechanisation of HPM damaging and disturbing the target,and the principle of Gaussian distribution effect of microwave density in the transmission process of HPMW was applied,and the critical boundary model of HPMW was established by choosing the threshold of microwave damaging the target as the main basis. The critical boundary model of a vertically launched weapon was divided into a vertical ascent section and a turning section from the aspect of perturbation factors,and the safety threshold of the critical boundary model of a vertically launched weapon was calculated with the help of Monte Carlo numerial analysis method. The shortest distance between the ideal ballistic trajectory and the HPMW antenna axis based on ballistic prediction in cooperative air-defense operations was described. The relationship between the set safety threshold and the shortest distance was used to determine whether or not fire conflict occurs. The simulation results show that the model describes the critical boundary of HPMW more accurately and reduces the loss of shootable airspace,and it can effectively give a more reliable conflict warning signal.
