Optimization of Speed Adjustment Strategy for Double-speed Acoustic Homing Torpedo

Solution of initial shoot parameters depends on the speed adjustment strategy of a multi-speed acoustic hom-ing torpedo. This study is on the premise that the torpedo-target distance as the multi-speed torpedo changes its speed is longer than the torpedo alarm distance of opponent submarine. A speed setting scheme of the double-speed torpedo is obtained for specified situation by analog calculation taking shorter attack time and longer surplus range as objective. Simulation result shows that the speed setting scheme is reasonable and convenient.
