中文摘要：
基于微波暗室静态测量数据,结合弹道学理论,分析了战术弹道导弹（TBM）弹头在再入段的运动学特性和电磁散射特性。研究表明,典型战情下再入舱的RCS比弹头目标的RCS大10～30dB。当采用LFM波形时,会导致较为严重的旁瓣遮掩效应,即脉冲压缩后末修舱的旁瓣会遮掩邻近微弱弹头目标的主瓣,导致弹头漏检。从理论和仿真的角度分析了相关设计参数（例如带宽）以及伴随物相关参数（速度、相对距离、相对RCS等）对弹头目标CFAR检测性能的影响,并提出了改善检测性能的建议措施。
英文摘要：
Based on darkroom static measurement data and in combination with ballistics theory,kinematic and electromagnetic characteristics of a TBM warhead in the reentry phase is investigated in this paper.It is indicated that the RCS of the reentry capsule is larger than that of the warhead by 10~30dB.When the LFM waveform is adopted,the phenomenon of sidelobe screening will be induced,i.e.,the voltage of sidelobe of a larger target will exceed that of the main lobe of an adjacent weak target.Consequently,the warhead might be out of detection when a CFAR detector is employed.The influences of radar related design parameters（e.g.,pulse width）,and target related parameters（velocity,relative range,RCS,etc.） on the detection performance of the warhead are analyzed in detail and verified by simulations.The proposal to improve the detection performance is also presented.
