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 applied the reshaped algorithm to one-dimensional signals

we can get some groups of equations by taking 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.
