Abstract :
This work deals with the problem of estimating the directions of arrival (DOA) of multiple radar targets present in the same range-azimuth resolution cell of a surveillance radar by joint processing the sum (Σ) and delta (Δ) channel data. The AML-RELAX estimator, previously derived by the authors, is extended to a two-channel system, and compared to the classical monopulse system.
