Gain and Phase Calibration of Uniform Rectangular Arrays Based on Convex Optimization and Neural Networks
A calibration method based on convex optimization (CVX) and neural networks is proposed for the large planar arrays of phased array three-dimensional imaging sonar systems. The method only needs an acoustic calibration source at an unknown position in the far field, and the direction of arrival (DOA...
