激光对红外成像制导跟踪系统的干扰技术研究

Reasearch on Jamming of Infrared Imaging Guided Tracking System by Laser

激光武器作为一种新型的光电对抗武器越来越受到人们的重视,但作为红外波段的干扰武器,目前研究甚少。本文以红外成像制导武器跟踪系统及其核心部件硅CCD为研究对象,对制导原理进行了概括,提出了激光干扰红外成像制导系统的三种途径。实验室以发射波长为10.6μm激光器作为干扰源对红外成像探测器及跟踪系统进行了干扰试验,给出了干扰效果图,并对影响干扰效果的因素进行了分析。

As a new type of opto-electric countermeasure weapon, the laser weapon is being taken more seriously. But as a jamming weapon in the infrared waveband, it is rarely reported at present. In this paper, the tracking system of an infrared imaging guided weapon and its core device, a silicon CCD axe used as the objects of study. The principle of infrared imaging guidance is summarized and three approaches to jamming the infrared imaging guidance system by using a laser are proposed. Jamming experiment is made on the infrared imaging detector and tracking system by using a 10.6μm laser as the jamming source. The images displaying jamming effectiveness are given and the factors which have influence on the jamming effectiveness are analyzed.
