Paper Abstract

Pre-processing radar signals incident on an adaptive array by applying an invertible transformation such as wavelets are the focus of this study. The effect of wavelet subband decomposition of radar signals prior to adaptation using an LMS algorithm or an Applebaum processor on the adaptation rate of these processors is examined. The performance of wavelet transform based array processors is compared with that of the FFT and cosine transform. The dynamic range of the array weights before and after wavelet transformation is being examined. Simulations involving experimental radar data and different types of wavelets are also presented.
