激光引偏干扰中漫反射板假目标的布设方法

Layout of diffuse reflection board used for laser decoying

激光引偏干扰是一种对抗半主动激光制导武器的有效手段,漫反射板假目标是激光引偏干扰系统的标准配置设备,为了提高漫反射板假目标在激光引偏干扰中的诱偏效果,研究了漫反射板的布设方法。根据半主动激光制导武器的来袭威胁信息和漫反射板的反射特性,分析了漫反射板假目标的布设位置、漫反射面的朝向和多个假目标布设的具体要求,给出了量化的约束关系式,并指出了实际布设过程中的近似处理方法。研究结果对于漫反射板假目标的布设具有理论指导意义。

Laser decoy jamming is an effective countermeasure for semi-active laser guided weapon. Diffuse reflection board used as the false target is one of standard parts in laser decoy jamming. In order to improve decoy effect of dif- fuse reflection board during laser jamming, the layout of the diffuse reflection board is researched. According to the threatening information of semi-active laser guiding and the reflective characteristic of diffuse reflection board, the con- crete layout of the diffuse reflection board including its position, reflection orientation, and number of reflection boards are analyzed. The quantitative restriction expressions are further provided. The research provides an theoretical refer- ence for diffuse reflection board layout for field test.
