以对映体干扰作战效能为研究目标,根据对映体干扰的基本原理,通过对对映体干扰作战过程的建模分析,得到了镜面反射和漫散射两种地形特征下的评估模型,提出修正的粗糙面漫散射模型,进而得到雷达跟踪角误差与干信比的关系模型。仿真结果表明同等粗糙度下,海面上的干信比要优于干沙地,同一表面上,粗糙度越小,干信比越大;用此模型可以精确预测对映体干扰对抗主动或半主动导弹的作战效能。

Focused on the problem that terrain bounce jamming (TBJ) disturbs combat efficiency, based on basic principle of TBJ, the operation process of TBJ was analyzed and modeled, and the specular reflection and diffuse reflection models were obtained, and the correctional diffuse reflection model for rough surface was proposed. Then the relational model between radar tracking angle error and jamming-to-signal ratio (JSR) was acquired. The simulation results show that the JSR for sea surface is superior to dry sand surface with the same roughness degree, but for the same surface, the smaller the roughness degree is, the bigger the JSR is. We can use this model to measure combat efficiency for TBJ against air-to-air missile with monopulse radar seeker.
