本文介绍了目标激光散射图象及特征的测量和提取的方法及实验结果,它们是激光雷达目标识别及激光武器系统的设计、使用和性能评价工作的基础。文中还分析了Speckle噪声对目标激光散射强度测量的影响,并指出在目标散射图象的测量中,Speckle噪声的影响可以通过相关滤波来消除。
This paper introduces the methods and experimental results of measurement and extraction of target laser scattering images and their characteristics, which are the basis of laser radar target recognition and laser weapon system design, use and performance evaluation. The effect of Speckle noise on the target laser scattering intensity is also analyzed. It is also pointed out that the speckle noise can be eliminated by the correlation filtering in the measurement of the target scattering image.
