Abstract
An application of a multistatic sonar concept is presented. Signal excess areas were simulated for a given configuration of one active source and two passive receivers for different sonar, target and sound speed profile parameters. Time delay estimation algorithm based on convolution in frequency domain is developed. Experimental results are given with real sonar measurements and time delay estimation in test tank and at sea trial.
