摘要
针对最小方差无失真响应(minimum variance distortionless response,MVDR)方法在信源方位快速变化情况下稳定性差的问题,提出一种解析小波域MVDR自适应波束形成方法,可在单次快拍条件下获得最优解。仿真及试验数据处理结果表明,解析小波域MVDR自适应波束形成方法在信源方位快速变化时较MVDR方法具有更好的目标检测和方位分辨性能。
Aiming at the minimum variance distortionless response algorithm has poor stability in the presence of fast moving sources,an analytic wavelet domain MVDR algorithm is proposed.It can get the optimum solution with single snapshot data.Computer simulation and experiment data processing results show that analytic wavelet domain MVDR algorithm has better target detection and azimuth resolution in the presence of fast moving targets.
