Simulation Algorithm on Kill Probability of Air-to-air Missile

摘要

We discuss the algorithm in two regions: the direct hit region and the near region where the proximity fuze can be detonated. The difficulties in computing the kill probability of air-to-air missile which warhead is composed of discrete rods are calculating the trajectory of each rod. The radial tracker arithmetic operations are to project the target's parts to certain coordinate plane along the radial direction and then to judge whether or not the intersection point of radial and projective plane is within the objects projective area. Some criterion of intersection between radial and limitary object are presented. The Monte Carlo method is applied to kill probability simulation as well as an model based on MATLAB is built. The simulation result shows that the kill probability of missile to a kind of helicopter is 0.9476 under a certain condition.
