摘　　要：随着远程打击武器突防能力的不断提高,其在对特定目标的打击过程中形成的群目标环境越来越复杂。为了能够及早发现关键目标,达到快速发现拦截摧毁的目的,导弹预警系统对雷达太空态势感知能力的要求越来越高。基于此,针对远程打击武器飞行过程中的特点,结合雷达基本原理,对影响雷达分辨能力的关键参数进行了简要分析,提出了基于背景熵的群目标判断方法,分析了基于OS-CFAR的密集群目标检测原理方法,讨论了大小目标近距离情况下基于Clean算法的遮蔽目标检测技术。With the continuous improvement of the penetration capability of long-range strike weapons, the group target environment formed in the course of striking specific targets becomes more and more complex.In order to detect key targets early and to achieve interception and destruction quickly, missile early warning system requires higher and higher radar space situational awareness ability.Therefore, in view of the characteristics of the long-range strike weapons in the flight process, combined with the basic principle of radar, the key parameters that affect the resolution of radar is briefly analyzed, a group target judgment method based on background entropy is proposed, and the principle and method of dense group target detection based on OS-CFAR are analyzed.The detection technology of shadowed target based on Clean algorithm is discussed in the case of large and small targets at close range.
