| 摘要: |
| 针对前向阵的杂波分布特性, 给出了一种空时自适应处理(STAP)结合多重中脉冲重复频率(MPRF)的处理方案, 研究了重复频率的选择以改进系统性能, 并分析计算了三路多普 勒通道联合处理STAP方法在一组中脉冲重复频率下的改善因子和距离/速度二维盲区分布图。理论分析与仿真结果表明, 该方案可以大大改善机载前向阵雷达的全程检测性能。 |

| Abstract: |
| The STAP of the forward looking airborne radar (FLAR) is studied. A scheme is presented, which is processed by the way of STAP combined with using multiple staggered medium pulse repetition frequencies (MPRFs). In addition, the selection of PRFs is further discussed to make the scheme more available for FLAR. The performance and range/velocity blind zone of FLAR are also investigated by using 3-C approach. The experimental simulation results suggest that the scheme can improve the detection performance in all interesting ranges for FLAR. |
