In many applications, the practical usefulness of adaptive arrays is limited by their
convergence rate. The adaptively controlled weights in these systems must change at a rate …

An investigation of the effects of system and medium perturbations, and the deviations of
signal field statistics from usual assumptions, on the performance of adaptive arrays is …

Digital control of adaptive arrays has been shown to be a feasible alternative to analog
feedback-loop control. As the eigenvalue spread of the correlation matrix no longer controls …

This paper reviews the principles of adaptive radar in which both the spatial (antenna
pattern) and temporal (Doppler filter) responses of the system are controlled adaptively. An …

The use of adaptive linear techniques to solve signal processing problems is needed
particularly when the interference environment external to the signal processor (such as for …

When an adaptive array operates in the presence of white noise only, the resulting beam
pattern is referred to as the quiescent response. Typically, these patterns have mainlobe and …

Adaptive array antenna systems are currently the subject of intense interest and
investigation/development for radar and communications applications. The principal reason …

The effect of random errors in the steering vector of an Applebaum adaptive array is
examined. Each component of the steering vector is assumed to have a random error …

This book is intended to serve as an introduction to the subject of adaptive array sensor
systems whose principal purpose is to enhance the detection and reception of certain …

A beamforming structure is presented which can be used to implement a wide variety of
linearly constrained adaptive array processors. The structure is designed for use with arrays …
