目标测偏统计用于对成像制导的激光干扰效果分析

Analysis on Laser Disturbing Effect on Imaging Guidance by Statistics of Target Measurement of Deviation

对成像制导武器的激光干扰是一个复杂的过程,当干扰源或干扰对象的参数以及两者之间的相对关系发生变化时,都会对干扰效果产生影响。提出了一种基于目标图像测量统计的干扰效果评估方法,对CCD成像探测系统的激光干扰进行了仿真试验,结果表明目标测偏量的均差和方差能够直接反映CCD成像跟踪系统在激光干扰下的受干扰程度,是对成像制导的激光干扰效果分析的一种有效途径。

Laser disturbing effect on imaging guidance can be influenced by parameters of laser or CCD and their relative rela- tionship. A method of laser disturbing effect evaluation based on target image measurement stastics is presented. By experi- ment analysis, it is shown that the divided difference and variance could directly reflect the disturbed degree of CCD image tracking system under the laser disturbing. The experimental results show that the method is effective for laser disturbing effect evaluation on imaging guidance.
