Aiming at the problem of matching between the scanning frequency and the speed of the motor of a single beam pulse laser detection system, the research on target deteetion of the single beam pulse laser detection system is carried out. In order to improve the detection probability of the laser detection system, a model of the missile＇s target intersection is established. The influence of laser pulsed frequency and motor scanning speed on the detection target probability of the circumferential detection system is analyzed by using Monte-Carlo method. According to the optimal laser pulsed frequency and motor speed, the principle prototype is designed and the simulating experiment is carried out. The experimental results show that in the case of 3 m detection range the detection system can detect the target effectively when the laser emission frequency is 20 kHz and motor speed is 30000 r/min, which provide the basis for the optimum laser emission frequency and the scanning frequency of the motor for the single pulse laser.
