| 摘 要： | 在单基侧视机载或星载雷达系统中,空时自适应处理是一种成熟可行的慢速移动目标检测方法。在双基雷达系统中,由于杂波的非平稳特性,空时自适应处理无法获得理想的性能。为了揭示双基雷达杂波的非平稳特性,文中推导出了方位-多普勒曲线,研究了一种基于AD曲线配准的杂波非平稳特性的消除方法,给出了此种方法的处理步骤和性能分析。通过仿真发现,该方法处理算法不太复杂且性能优良。

| Abstract: | In sidelooking monostatic airborne or spaceborne radar systems,Space-Time Adaptive Processing(STAP) is a mature detection method for slow moving targets.In bistatical radar systems,the desired STAP performance cannot be obtained because of clutter non-stationarity.To reveal the non-stationarity of bistatic radar clutter,this paper derived azimuth-Doppler curves.On the basis of this,a mitigation method based on curve registration for non-stationarity of bistatic STAP radar clutter is studied.The paper gives processing steps and performance analysis of the method.Simulations show that the processing algorithm of the method is not very complex and its performance is fairly good. |
