Formulating wideband array-pattern optimizations

Abstract

Custom design of wideband digital array patterns requires a systematic approach to mapping design specifications to a program understandable by optimization engines. We show that, as in the narrowband case, wideband array patterns are closely related to multidimensional FIR filter responses, suggesting the adaptation of powerful and efficient filter design techniques to the array problem. Previously reported FIR filter design techniques are then applied to an example array-pattern design.
