Title Study on detection range near infrared target for near infrared
Abstract
Abstract：The traditional indoor test of the infrared search and track system usually uses a test device with several collimators，which are fixed at different azimuth and pitching angles．The test device is not suitable for short distance indoor experiments because of its low accuracy，huge size and uneasiness to move．The proposed small target track simulation system drives the small target disk by a precise stepping motor．The blackbody radiation sources provide target temperature．PC connects the stepping motor through RS-232 serial interface，then turns them into azimuth and pitching angles through the measuring angle algorithm．Comparing the azimuth and pitching angles measured by the infrared search and track system with the theoretical value then the tested system S precision is gained．The design and implementation of the small target track simulation system are discussed in detail．Analysis for the experiment resuhs is also presented．
Key words：small target simulation；azimuth；pitching angle

1．1 课题背景及意义
随着近些年来科技的发展，导弹技术的日益进步，精确制导也就变得尤为重要，对于空间中移动的目标的搜索也很自然的成为了现代战争的重中之重，红外探测器制导可以引导导弹飞向正确的目标位置以击中目标，所以红外探测器作为精确制导武器的重要组成部分，也在军事制导、定点打击方面扮演着越来越重要的作用。随着近年来红外焦平面器件的发展，各种智能型红外搜索跟踪系统竞相问世，在航空、航天以及军事等领域发挥着越来越重要的作用。智能型红外搜索跟踪系统的出现，对传统的测试手段提出了挑战[1-3]。
