The Simulation of Submarine Avoiding Passive Sonobuoys Dectection Under Different Speed and Sea State Level

摘要

The submarine's radiated noise is the signals that the passive sonobuoys detect and track targe and will be changed with its motion velocity. The ocean environment characters such as the sea state also have influnce on the submarine avoiding the passive sonobuoys detection. The models of the submarine's motion and the sea state were established, and according to the passive sonar equation and the detection theory, the submarine's evasion effection were researched and simulated. The results show that the speed and the sea state have an important effect on the submarine's evasion, which is significant for subamrine's hydroacoustic counterment.
