The models of square search, sector search and spiral search were firstly established. Based on the models, the effects of search efficiency of dipped sonar along with the changing moving velocities and courses of submarine were analyzed respectively. Lastly simulations results showed that searching probability of dipped sonar decreased with the increase of submarine’s velocities and courses, and that the effect on the searching probability of dipped sonar was lesser than that of square search and sector search, and that when submarine evaded with full speed far away from the current dipped point, the searching probability would be reduced obviously. It was of practical guiding significance for submarine fighting against dipped sonar.
