根据复合热成像侦测系统的配置和特点,需要高分辨力系统实时地提供来袭目标的准确位置,即目标的方位角和俯仰角来引导伺服系统完成对来袭目标的精确跟踪,保证系统实施战术干扰对抗所需的高精度。文中给出了角度测量的方法,即由视轴中心位置和角度偏差量合成目标位置,而角度偏差量由脱靶量转换得到,脱靶量的准确测得需要对目标图像信号进行实时处理,并且要把脱靶量的延时辨识出来。
According to the configuration and characteristics of the complex thermal imaging detection system, high-resolution system is needed to provide the exact location of incoming targets in real time, that is, the azimuth and pitch angle of the target to guide the servo system to accurately track incoming targets and ensure that the system Tactical interference required to implement the high precision. The method of angle measurement is presented in this paper. That is, the target position is synthesized from the position of the center of the optic axis and the angle deviation, and the angle deviation is converted from the miss distance. The accurate measurement of the miss distance needs to process the target image signal in real time, Identify the delay of miss distance.
