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。
Laser stealth technology can reduce the reflective properties of the target at the working wavelength of the laser, thereby weakening the detection capability of enemy laser detection devices and effectively protecting one’s own goals. The objective of the laser stealth effect assessment for the development and application of laser stealth technology plays an important role in the LRCS is to describe the target of the incident laser scattering ability of the physical quantity, according to the characteristics of the battlefield laser signal, the proposed stealth front and back , The change of the target laser radar cross-section in different reflection directions to describe the stealth effect of the laser, the stealth effect evaluation in the research and development stage, and the non-stealth target as the assessment benchmark; for the stealth effect evaluation in the application stage, the standard diffuse reflector is used as the evaluation Benchmark, in order to achieve the target laser stealth effect assessment. The assessment method can fully assess the description of the laser stealth effect, with good operability.
