Modeling and Simulation of Underwater Sonar Array Detects Radiation Noise of Aerial Target

In order to research the feasibility of underwater sonar array detects radiation noise of aerial target, it founds model of sound transmit from air to seawater, ambient noise of ocean(NL), detect threshold(DT) and direction index(DI) of underwater sonar array, gets quantificational result through modeling and simulation means.receives the result of detection distance curve when DT or DI of underwater sonar array change.Draw the conclusion:it is difficult to detect or achieve long-distance alertness to aerial target by underwater sonar array under detection mode in existence.
