| 摘 要： | 研究了均匀圆形天线阵列STAP处理中一种改进的直接数据域方法. 该方法仅通过幅度加权即能有效抑制杂波和干扰，实现对目标信号的正确估计. 当目标信号的方向与天线波束指向有偏差时，采用多约束的方法，保证系统在目标信号方向的增益. 实验结果表明了该方法的有效性.

| Abstract: | In this paper, an improved direct data domain method is studied for airborne radar with uniform circular array antennas in STAP. Based on a single snapshot, this algorithm can effectively restrain jamming and clutter while keeping the signal of interest. By implementing multiple space-time constraints, the system gain is maintainedwhen the signal of interest deviates slightly. Experimental results show effectiveness of the method. |
