摘　　要：为了科学评估激光角度欺骗干扰系统的防护能力,有必要考虑激光告警对干扰的引导这一重要环节。根据散射探测原理建立了6个窗口的激光散射告警装置的告警模型,并根据激光制导武器的攻击方向与激光指示方向的关系,以及漫反射板的防护能力,建立了告警引导下的防护覆盖率计算模型。以此分析了告警定向结果,评估了告警引导下的激光欺骗干扰系统的防护能力。结果表明:告警引导干扰激光照射3个均匀分布的固定漫反射板时,防护覆盖率为78.1%;如果能够根据告警结果调转漫反射板的方向,则只使用一个漫反射板,防护覆盖率也可以提高到98.2%。此研究为激光角度欺骗干扰系统的使用和防护能力评估提供了理论基础。In order to scientifically evaluate the protection ability of the laser angle deception interference system,it is necessary to consider the important link of laser warning to guide the interference.Firstly,according to the principle of scattering detection,the warning model of laser scattering warning device with six windows was established.Secondly,according to the relationship between the attack direction of laser-guided weapons and the direction of laser indication,as well as the protection ability of diffuse reflectors,a calculation model of protection coverage under warning guidance was established.On this basis,the results of warning orientation were analyzed,and the protection ability of laser deception interference system guided by warning was evaluated.The results show that when the warning-guided interference laser irradiates three fixed diffuse reflectors with uniform distribution,the protection coverage is 78.1%.If the direction of the diffuse reflector can be adjusted according to the warning results,only one diffuse reflector will be used,and the protection coverage can also be increased to 98.2%.This study can provide a theoretical basis for the use and evaluation of protection ability of laser angle deception interference system.
