Abstract : The principal object of the invention is to provide time and space Fourier transform signal processing for sonar arrays. Another object is to provide Fourier transform processing that is an improvement over conventional time delay beam forming followed by frequency analysis. A further object is to provide multi-dimensional Fourier transform processing by coherently re-mapping and thereby preserving phase and amplitude, from the output of one stage of processing to the input of a second stage.
