Array failure correction with a digitally beamformed array

Array failure correction with a digitally beamformed array

A technique is presented for replacing the signals from failed elements in a digitally beamformed receive array. The technique is shown to be useful in a multiple signal environment and does not impose special restrictions on the correlation properties of the received signals. Experimental data conf...

description A technique is presented for replacing the signals from failed elements in a digitally beamformed receive array. The technique is shown to be useful in a multiple signal environment and does not impose special restrictions on the correlation properties of the received signals. Experimental data confirm the operation of this algorithm for the case of one signal and one interfering source. The technique is shown to be accurate when the incident signal locations are not precisely known, and even when the signals are distributed over a broad angular region or are only known to be located within a broad angular region.
