Adaptive Lattice Algorithms for Passive Array Data

Abstract

This paper reports the development of an algorithm for the processing of data from an array of broad-band sensors using lattice type processor. The problem is to enhance the look-direction signal in the presence of spatially distributed interference sources and sensor self noise by employing a multi-channel processor subject to the constraint that it has a desired response for look-direction signals. The multichannel lattice algorithm proposed here possess stage by stage decoupling, and do not involve an arbitrary size of the step length, unlike conventional tapped-delay-line algorithms.
