摘　　要：雷达对抗侦察装备的作用是对敌方雷达辐射源信号进行参数测量、目标识别,是雷达电子战装备的重要组成。为了提高分选技术的水平,国内外学者提出多种信号侦查算法,现分选技术能够适应特殊体制雷达信号,但信号增批的问题仍然普遍存在,在演习训练和例行侦察任务中,严重影响雷达对抗情报分析人员和电子战行动指挥员掌握雷达目标特性和电磁态势。文中从雷达对抗侦察的工作原理入手,从系统角度进行分析,结合电磁波传播机理和实际作战运用环境,全面深入分析了侦察信号增批的原因,并针对性地给出复杂电磁环境下的改进建议,可以使雷达对抗装备乃至操作人员更好应对信号增批带来的不良影响,对于改进雷达对抗侦察装备性能,提升其复杂电磁环境适应性具有十分重要的现实意义。The role of radar countermeasure reconnaissance equipment is to measure the signal parameters and identify the targets of the enemy′s radar radiation source,which is an important component of radar electronic warfare equipment.In order to raise the level of sorting technology,scholars at home and abroad have put forward a variety of signal detection algorithms.The present sorting technology can adapt to the radar signals of special systems.However,the problem of increasing⁃batch of signal is still existed commonly,which seriously affects radar countermeasure information analysts and electronic warfare operation commanders to grasp the radar target characteristics and electromagnetic situations in exercise trainings and routine reconnaissance tasks.This paper starts with the working principle of radar countermeasure reconnaissance.In the perspective of the system,the causes of increasing⁃batch of the reconnaissance signals are analyzed comprehensively and deeply in combination with the electromagnetic wave propagation mechanism and actual combat environment.In addition,some improvement suggestions against complex electromagnetic environment are given accordingly,which can make the radar countermeasure equipment and even the operators better deal with the adverse effects of signal increasing⁃batch,and is of great practical significance to improve the performance of radar countermeasure reconnaissance equipment and enhance its adaptability to complex electromagnetic environment.
