Abstract :
Since the sea echo is one dimensional signal, this paper, based on an arbitrary triangular array, presents that Space-Time DOA Matrix Method, which is originally used to estimate two dimensional angles of arrival under ideal conditions, can be reshaped to be used under amplitude and phase errors. When we apply the reshaped algorithm to one dimensional signals, some groups of equations can be obtained by taking the use of redundant information and then estimate the array´s amplitude and phase errors simultaneously so as to achieve self-calibration. Its validity is verified not only by Computer simulation, but also by comparing treatment results of measured data before and after calibration with the GPS-measured result.
