Radar signal processing architectures and algorithms in digital VLSI (Very Large Scale Integration)

The revolution recently wrought in signal processing by the Fast Fourier Transform (FFT) algorithm and the technology of digital integrated circuits is realized as merely the harbinger of an even more profound change involving not only a new generation of very large scale integration (VLSI) technology and algorithms properly optimized in the numerical analysis sense but also computers organized in new ways to distribute the processing load among many active elements operating concurrently. This realization stimulated a study to evaluate the likely impact of these developments, point out priorities and to make recommendations as to the research areas on which to concentrate resources. The modern signal processing techniques which are likely to provide adaptive processing, optimum estimators in angle of arrival and frequency and other functions are documented. Numerical techniques are applied for least squares minimizations, singular value decomposition, eigenvector decomposition.
