Research on Submarine Search Technology of Maneuver Avoidance with Ship and Aircraft Coordination

Abstract

In order to avoid the low efficiency of submarine search by single-base hoisting sonar, a combined dual-base searching method of towed sonar and helicopter hoisting sonar is introduced. Firstly, according to the marine environment, BELLHOP model is used to obtain the curve of search distance with water depth. Secondly, according to the submarine’s initial position point, sailing speed, helicopter’s cruising speed and the average flying speed between hoisting points and other information, the active and passive joint search models with extended square, extended circle and extended spirality are established.Finally, combining the submarine evasion model, using the Monte Carlo method, the influences of call point distance, submarine initial position distribution and submarine speed on submarine search efficiency under different formations are simulated.The simulation results show that considering the simulation results under the condition of submarine movement, compared with the single-base search, the dual-base search has higher search probability for evading submarines.
