Abstract :
This paper presents a new linear matched field processing (MFP)algorithm that is based on environmental perturbation in shallow water. The algorithm can achieve higher probability of correct localization than conventional Bartlett processor with environmental mismatch. The paper also presents a linear matched field algorithm based on postbeamformer interferences canceller (PIC) to null interference. The high sidelobe of this algorithm can be overcome by broadband processing
