Echo analysis of High-repetition-rate Laser Detection and design requirements of detection system

通过分析高重频激光探测的作用原理,并利用目标回波功率的计算方法,对不同能见度条件下目标回波功率随探测距离的变化情况进行了仿真;分析了近程大气的后向散射、大气湍流以及系统噪声对目标回波信号的接收以及探测系统可能造成的影响,进而有针对性地提出了探测接收系统的基本设计要求,为提高主动探测系统的探测能力提供了参考依据。

Through analyzing the principle of Laser active detection,and using the calculation formula of target echo power,the change of echo power along the detection range in different visibility conditions is simulated.The possible influence of backward scattering,atmospheric turbulence and system noise on target echo and the detection system is analyzed.At last the basic design requirements of the detection system is proposed and it provides a reference to improve the detecting ability of active detection system.
