Multiple Channel Adaptive Filtering Using a Fast Orthogonalization Network: An Application to Efficient Pulsed Doppler Radar Processing.

Abstract

A numerically efficient algorithm is developed for adaptively filtering multiple input channels into desired multiple output channels. The algorithm is a type of adaptive lattice filter which employs a Fast Orthogonalization Network (FON) algorithm for numerical efficiency. Past researchers have concentrated on developing efficient lattice algorithms for the processing of stationary input channels; i.e., the input covariance matrix is Toeplitz in form. The algorithm developed in this report is designed to adaptively filter nonstationary input channels. Various implementations of the FON algorithm are given, and a performance measure based on the number of operations is formulated. An application of the technique to adaptive doppler processing presented. (Author)
