The basic goal of this research was to study the role that wavelet theory can play in information representation and extraction. The researchers focused their attention primarily on surveillance applications. As part of their research, they studied two problems that arise in surveillance. The first problem was that of determining the directions of arrivals of a set of plane waves in the presence of a background noise of unknown correlation structure. The second problem involved selecting an optimal set of N waveforms, with N fixed, to obtain the best reconstruction of a distributed range-doppler target reflectivity function.
