From the definition of unidirectional hydrophone,its application is analyzed in underwater beamforming,and by using the unidirectional hydrophone constructs the ten-element double circle array. Based on this array,an experiment is finished in anechoic water pool,which is investigated to verify the unidirectional hydrophone used in underwater beamformer of validity and practicability. In this dissertation it is proved by theory,computer simulations and real-data processing that unidirectional hydrophone is feasible solution for beam optimization and improves the performance of the beam pattern with strong robustness.
