Wavelet spatial filtering and transient signals
Joel A. Rosiene · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1996
The definition of a spatial filter using wavelets is presented. The technique is of the same order as a frequency domain beamformer, O(N log2 N). The array's beam response to the wavelet is defined and the beam response for a linear array of sensors to a wavelet is presented.
