Adaptive two-dimensional harmonic retrieval and its application to radar
Abstract
Estimation of the frequency and the angle of arrival of point-source emitters is viewed as an application of two-dimensional spectral analysis. In this paper, stochastic gradient and approximate least-square algorithms for adaptive two-dimensional harmonic retrieval are derived. These algorithms extend the results obtained by Reddy et al. (1982) to the two-dimensional case.
