Research on Optimum Operating Parameters Selection of Active Sonar in Shallow water

The selection of working parameters of active sonar, especially the selection of working frequency and working depth, has a great influence on the performance of sonar detection. An active sonar detection performance evaluation model is established in this paper based on sonar equation and propagation model. Connecting with the inherent characteristics of the equipment, the transmission loss of different frequencies and depths at different distances is transformed into detection probability, and the performance evaluation objective functions at different frequencies and depths are obtained by integrating detection probability. The optimal operating parameters of active sonar in shallow water under several typical hydrological conditions are simulated and verified by numerical calculation.
