摘要
针对高分辨率雷达(HRR)目标检测问题,提出了一种多脉冲下扩展目标广义似然比检测方法.该方法首先对各距离分辨单元在方位向进行非相参积累,然后利用类似单个脉冲下扩展目标的广义似然比检测器来实现高分辨率雷达的检测.理论分析和仿真结果表明,该方法可明显提高高分辨率雷达的检测性能.
Aimed at the detection ot HRR target, a novel algonmm was proposeo oaseo on me generalized likelihood ratio test （GLRT） of the multi-pulse spread targets, First, each range resolving unit was accumulated noninherently in azimuth, and then the detection of HRR target was done with the GLRT detector similar to that of the mono-pulse spread targets. Theoretical analysis and simulation results show that the proposed algorithm can significantly improve the detection performance of HRR.
