摘　　要：对于窄脉冲激光探测系统,当激光经探测目标不同散射面元散射后到达接收机的时间差大于发射激光脉冲宽度时,存在激光回波脉冲宽度展宽和相应峰值功率下降问题,加上激光接收机响应带宽的限制,由此,对探测目标的等效LCS不能简单地由一般的公式计算。在考虑以上因素的情况下,本文对朗伯散射体等效LCS的计算方法进行初步探讨。To pulse laser detecting system,when the optic path time difference with different scattering area elements is larger than the shooting laser pulse width,the back laser pulse width will be broaden,and the corresponding pulse peak power will be lower,adding to the limited receiving bandwidth,the target equivalent LCS can't be calculated using the general formula.In the paper,the calculation about Lambel target equivalent LCS considering the above factors is discuss .
