摘　　要：针对近程导弹告警设备目前采用的连续扫描型存在成像质量不高和固定凝视型成本过高的问题,对一种面阵红外CCD探测器的探测方法进行了研究。提出将先进的非等速步进准凝视图像采集控制方法用于一种复合式小型导弹告警系统中。对常规控制方法和步进准凝视控制方法进行了比较,重点解决了该控制技术在红外探测系统中的应用。此方案在某型在研告警设备中进行了实验,方位误差限定在0.4mrad条件下其分辨力可达0.01°。该控制方法可应用到其他告警探测设备的设计中。In view of the two disadvantages of current short-range missile warning equipment-one is that the scanning system can＇t get high quality image and the other is that the cost of staring system is too much, a scanning method about a kind of staring IRCCD detector was studied. The non-constant step-stare control method was applied to a small compound missile warning system. We compared conventional control means and step-stare control means, and focused on solving the application problem of the control technology in the IR scanning system. This project was used for a waning system. The distinguishing rate is 0.01° when the azimuth error is limited at 0.4mrad.The control method can be also applied to other warning detection equipments.
