Design Considerations of a Programmable Predetection Digital Signal Processor for Radar Applications.

Abstract

Signal processing tasks normally encountered in a radar system, such as pulse compression and moving target indication, are defined in terms of recursive and nonrecursive digital filtering and the discrete Fourier transform. Analysis of these algorithms reveals that the general second-order recursive filter and the Fast Fourier Transform butterfly are kernels which should be efficiently executed by a Radar Arithmetic Processing Element (RAPE). This element would be the arithmetic unit of an envisioned programmable signal processor. With associated memory and a small microprogrammed control unit, this element could be an independent, general-purpose signal processor. As such, it may represent an off-the-shelf module capable of replacing a wide range of existing special-purpose hardware. (Author)
