Abstract: A scheme to evaluate the damage efficiency is presented for studying the damage efficiency of terminally sensitive submunition scanning in the ascent. A damage efficiency evaluation model is proposed by establishing a scanning recognition model, a hitting model and a tank target damage model for terminally sensitive submunition scanning in the ascent, and the damage efficiency evaluation process based on Monte Carlo method is presented. The scanning recognition probability and hit probability of terminally sensitive submunition scanning in the ascent under the conditions of different initial disturbance, rotation speed, missile-target distance and target speed are calculated, and the damage efficiency of terminally sensitive submunition scanning in the ascent is evaluated. The change rules of the damage effectiveness of terminally sensitive submunition scanning in the ascent with initial disturbance, rotation speed, missile-target distance and target speed are obtained. The analysis results show that the scanning recognition probability decreases with the increase in initial disturbance and target speed, and increases with the increase in rotation speed. When the initial disturbance is not more than 0.5 rad/s and the speed is not less than 20 r/s, the recognition probability of tank target is more than 97.5%. The hit probability decreases with the increase in target distance and speed. The damage probability of terminally sensitive submunition scanning in the ascent against tank targets at different speeds is greater than 70%. Key
