Study On The Fuze-warhead Coordination Of Six Laser-range Finder And Aimed Warhead

In order to improve the damage probability of the antiaircraft rocket consisting of sixpulse-laser detection system and six quadrant fragmentation-directional warhead.This paperstudied the system including helicopter as well as the antiaircraft rocket, and set up a modelused to analyses that system. Mathematic models, such as the vulnerability model of armedhelicopter, the fuze simulation model, the model of the fragment motion, the model ofdetection target and the model calculating the damage effect on the target, were built. TwoMATLAB computer programme have been given, which can compute the detectionprobability and damage probability. Based on the Monte-Carlo method, the influence ofmany parameters on the detection probability and damage probability were studied.Simulation results show that the detection probability and damage probability both increaseas the rotation rate increases; Pluse frequence and velocity of helicopter have little effect onthe detection probability and damage probability. The distribution of optimal delay time aswell as detonation is obtained, and a table of the best azimuth is compiled.Simplifying the target, Optimal Delay and best detonate azimuth analytical expressionshave been derived. Numerical results showed that the damage probability was not highwhen directly using the derived expressions. A correction method was advanced, and thenumerical results illustrated the better effect than the previous method, more than5%in theengaged state and10%in the chase state.
