多径效应下雷达对抗侦察作用空间分析

Analysis for Zone of Radar Countermeasure Reconnaissance under Multi-Path Effect

雷达对抗在现代电子战中具有重要作用,无论是雷达对抗侦察还是雷达干扰,对其进行雷达对抗的空间能量分析具有重要意义,可为雷达对抗战斗部署提供依据。为了直观描述雷达对抗侦察的有效作用区域,给出了雷达对抗侦察作用空间的定义,并分析了地面反射多径效应对侦察作用空间的影响。理论分析和仿真实验表明,多径效应使侦察作用空间分裂,产生侦察盲区,因此,在执行侦察任务进行侦察机配置时,应尽量避开侦察盲区。

The radar countermeasure is very important in the modern EW. The analysis for space power of radar countermeasure takes on significant for both radar countermeasure reconnaissance and radar jamming which can instruct radar countermeasure battle disposition. In order to exhibit the effectual zone of radar countermeasure reconnaissance,the definition of reconnaissance space is put forward,and the effect of multi-path by ground refection was analyzed. The theory and simulation indicated that the radar countermeasure reconnaissance space produced blind zone by the multi-path effect,and so the blind zone should be taken into account when collocating the reconnaissance receivers.
