Parallel spatial processing: A cure for signal cancellation in adaptive arrays
Young-Lim Su, Tie-Jun Shan, Bernard Carlos Widrow · IRE Transactions on Antennas and Propagation · 1986
A spatial processing algorithm with parallel structure is presented for the prevention of signal caneellation phenomena in conventional adaptive arrays. This algorithm basically uses a parallel structure with a spatial averaging effect to combat coherent jamming. It results in a spatially smoothed maximum-likelihood estimate of the desired signal when the adaptive beamformer converges. Simulations have been conducted which verify the effectiveness of the proposed structure.
