| 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。

| Abstract: | 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 warh... |
