Abstract: A new passive detection and location method for underwater targets based on the correlation metric of three signals received by three elements was proposed, and its advantages compared with two-element- correlation in detection performances were analyzed. The simulation was performed to verify the detection performances and time delay estimation accuracy. The simulation results show that, compared with two-element-correlation method, the modified method can improve the detection performance by 2 dB and the time delay estimation accuracy in a certain extent.
