从物理光学和辐射原理的角度分析了目标反射特性对激光末制导精度的影响 ,给出了目标反射系数的直接测量方法 ,最后得出结论并提出了减少受其影响的措施。分析结果表明目标反射特性会影响激光末制导炮弹的接收反射激光信号功率的大小 ,进而影响激光末制导炮弹的制导概率 ,因而对于不同质地的目标 ,要根据目标的反射系数来确定激光指示器可靠的照射距离 ,选择其照射攻击部位 ,以提高激光末制导精度。

Targets Reflection Characteristics to Accuracy of Laser End Guidance

Based on physical optics and radiation principles,this paper analyses the targets reflection characteristics influence on laser end guidance.Then it presents the direct measure methods for targets reflection coefficient,and finally gives the conclusions in which some methods to reduce the influence are provided.Moreover,the results indicate that targets reflection characteristics will affect the power of reflection laser signals received by laser end guidance bomb,and even the guided probability.Therefore,according to the reflection coefficient of various targets,we can determine the reliable illuminating distance of laser designator and chose the attack interface of targets to increase the accuracy of laser end guidance.
