摘要
实现声源的检测与定位,传统的阵处理方法是常规BF/MFP或基于子空间的BF/MFP,它们都是属于单分辨处理。事实上,阵信号中存在着多分辨结构,值得开发与利用,以提高检测与定位能力,且特别有利于改善BF和MFP的失配宽容性。本文对多路径传播波的时-空多分辨建模及相应的多分辨聚焦处理进行了研究,并对实际海试数据作了分析,结果表明改善了MFP模糊度表面的性能。
The conventional BF/MFP or BF/MFP based on subspace are traditional array signal processing methods for sources detection and location. They are all belong to singe-resolution processing. In fact, the array signal has multiresolution structure, which is worthy of exploiture and utilization to enhance the ability of detection and location, especially to improve the robustness for BF/MFP. In this article, the time-space multiresolution modeling of multipath transmitted wave and the corresponding multiresolution focused processing are investigated, and it is shown from the analysis of actual sea-trial data that the performance of MFP can be improved.
