| 摘 要： | 本文提出了一种时空二维信号的非自适应准最佳处理新方法。用时间和空间对消器分别对消掉与目标同方向的主杂波和与目标同多普勒频率的副瓣杂波,然后用时间和空间滤波器滤除其余杂波,与其它方法相比,该方法运算量最小,能实现实时处理,且性能接近最佳。

| Abstract: | This paper presents a new non-adaptive quasi-optimal approach for temporal-spatial 2-D signal processing. A temporal canceller is used to cancell the mainlobe clutter which has the same direction as target, and a spatial canceller is used to cancell some side-lobe clutter which has the same Doppler frequency as target. Then the other clutter is filtrated by temporal and spatial filters. Compared with other approaches, this one involves the smallest computation, and makes real-time processing possible, while the system performance is proximally optimal. |
