Abstract—A robust Capon-type algorithm is constructed for source localization by a partially calibrated array operating in an uncertain environment. Results of statistical modeling are presented to determine the accuracy of source localization and the probability of correct source detection. Experimental testing of the proposed method is carried out to demonstrate its performance in Ladoga Lake.

Keywords: source localization, partially calibrated subarray-based array, robust algorithm, statistical modeling, experimental testing
