    Abstract

    Aiming at improving the damage probability of ground attack rocket effectively, the laser circular-viewing detection system was adopted to capture the target credibly. Computational formulas for the laser echo and the minimal detectable optical power were proposed to establish the model of the missile-target encounter based on the terminal trajectory characteristics of ground attack rocket. The change regulation of laser repetition frequency and motor scanning speed on the target capture probabilities using different detection systems were analyzed by using Monte-Carlo method to select the optimal repetition frequency and scanning speed. And the effects of rocket projectile velocity and hit accuracy on target capture probabilities were discussed. The experimental results show that the damage probability of single guided rocket projectile is increased effectively by using the laser circular-viewing detection system. Meanwhile the laser repetition frequency is 5 kHz, and scanning speed is 10 000 r/min. Simulated outcome provides the basis for the application of the laser circular-viewing detection system on guided rocket projectile.
