复合热成像侦测系统的角度测量

Angle Measurement of the Compound Thermal Imaging Detect System

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 features of the compound thermal imaging detect system, it needs the high-resolution system to supply the exact position of attacker at any time, which is azimuth angle and pitch angle of the target, in order to guide servo system to track attacker exactly, and assure system of high precision when implementing tactic interference. The method of angle measurement is given, it uses the center of optical axis and the angle deviation to synthesize the position of the target, the angle deviation is converted by miss distance, the exact measurement of the miss distance needs real-time process of the target＇ s image signal, and identification of the time-delay of the miss distance.
