Target Depth

In order to distinguish underwater targets, the method of target depth resolution urgently need to be developed. Matched field processing (MFP) is a passive detection method and it can be used to distinguish two targets at different depth. In this paper single vertical array MFP simulation has been done for targets depth resolution while they have same distance and azimuth in ocean acoustic field and the results show that the resolution is basically correspond to theoretical value.
