摘　　要：基于火控理论中待机射击的特点,研究了具有随机特性的机动目标随机穿越射击域时的周期命中概率问题,即穿越周期内射击时间受限条件下的多发命中概率。通过导出目标随机穿越周期的多发命中密度函数和特征函数,得到了周期命中概率的一般表达式。通过算例分析说明了结论的正确性。Based on the characteristic of awaiting fire in the fire control theory, the problem of period hit probability to a maneuver target with properties of randomly passing through shot area was studied, that is, many hit probability under the condition of shooting time limited. The general expressions of the period hit probabilities many times under shot area were achieved through derived the density function in many hits to target with properties of randomly passing through shot area and its characteristic function. The calculated result of a practical example shows that the expressions are correct.
