| 摘 要： | 地面动目标检测(GMTI)是脉冲多普勒雷达的重要应用领域之一。星载稀疏孔径GMTI雷达系统比传统的机载系统具有更强的适应性和更好的检测性能而受到广泛关注。文中应用空时自适应处理(STAP)对星载稀疏孔径GM-TI雷达的动目标检测方法和性能进行了仿真研究;基于星载均匀直线阵列GMTI雷达系统,运用典型的STAP算法获得了目标检测的结果。进而对孔径位置偏差、相关处理间隔和脉冲重复频率等参数变化时系统检测性能进行了分析。

| Abstract: | Radar community paid much attention to spaceborne sparse aperture GMTI radar systems in recent years due to its high detection performance and adaptability compared with other airborne systems.In this paper, we apply some typical STAP algorithms to simulate the performance of spaceborne sparse aperture GMTI radar with antenna elements distributed uniformly and linearly along the track,at the same time,we also analyze detection performance under the influence of aperture position error and the change of CPI and PRF. |
