Abstract

Ship is a complex underwater volume source in shallow water; its raidated noise field has the spacial directivity, which results in an obvious difference of detecting pefrormance of passive sonar at different aspect angles. In this paper the multi-poles mathematical model of the ship radiated noise fiels is established in shallow water, and the method of detecting probability for ship is researched using passive sonar equation. The detected probalility is estimated at different aspect angles when the range between receiver and the source is given, at the same time the obtained results are compared. These simulated results are of particular importance for the safety of traveling ship in the sea.
