激光隐身技术可以降低目标在激光工作波长处的反射特性，从而削弱敌方激光探测设备的探测能力,有效保护己方目标。对目标的激光隐身效果进行评估，对于激光隐身技术的发展和应用具有重要作用，激光雷达截面(LRCS)是描述目标对入射激光散射能力的物理量，根据战场激光信号的特点，提出利用目标隐身前后，目标激光雷达截面在不同反射方向的变化来描述激光隐身效果，对于处于研发阶段的隐身效果评估，以未隐身目标作为评估基准；对于处于应用阶段的隐身效果评估，以标准漫反射板作为评估基准，从而实现对目标激光隐身效果评估。该评估方法可以全面考核描述激光隐身效果，具有较好的操作性。

It is important to evaluate the stealth effectiveness for the developments and applications of laser stealth technology. Laser radar cross section (LRCS) is a physics parameter used to characterize the dispersion capability of an object on the incident laser signal. According to the characteristics of laser signals in the battlefield, the LRCS changes with different reflection angles are used to describe the laser camouflage. For the developing and application stages of stealth technology, the noncamouflage targets and diffusereflection board are used as the evalution standard respectively. This method can assess the effectiveness of target laser stealth comprehensively and has high operability.
