Abstract :
The authors view the interference as a stochastic process n (m,t) in two variables. They assume a uniform linear array that the carrier frequency is known and that the direction of arrival of the desired signal does not change. The approach is an application/extension of the multi-window method for spectrum estimation and harmonic analysis introduced by Thomson (Proc. IEEE vol.70, no.9, p.1055-96, Sept.1982). How the signal is estimated if present, and how to estimate the DOA, are discussed briefly
