| 摘 要： | 通过对调制对比度限制下的作用距离建模,文中分析了激光主动成像探测系统的性能.首先描述了系统组成,然后通过调制对比度的表达式导出了作用距离模型,最后根据"猫眼"目标和漫反射目标不同的特性分别进行了仿真计算.结果表明:激光主动成像探测系统基于"猫眼"效应探测时性能大大提高.

| Abstract: | This presentation analyzes the performance of laser active imaging detection system by giving a model of operation range based on limited modulation contrast ratio.Firstly,the structure of this system is described.The model of operation range is deduced according to the expression of modulation contrast ratio.The simulation for system performance is carried on with "cat-eye" target and diffuse target respectively.The result shows that the system performance are greatly improved when "cat-eye" target is detected. |
