摘　　要：研究了在一个固定区域对随机运动目标进行连续探测的概率时间收益问题。首先建立了"绝对连续探测"的概念,证明了在绝对连续探测条件下,在一个区域的持续探测,持续时间不会带来概率的增加。提出了"一次探测周期"概念,建立了一定"一次探测周期"时持续探测的概率与周期数的函数关系,并定义了持续探测概率的概率收益、概率时间收益率。算例表明了所定义各参数的基本变化形式。The probability increment with respect to detection duration in a specific limited space is studied. The new concept of “absolute continuous detection”is given,and in the condition of “absolute continuous detection”,zero probability increment with detection duration is proved.The concept of “one detection cycle”is given.A relation is established between the probability of detection duration and the number of cycles,and the probability increment and probability increment ratio of continuous detection are defined.The calculation sample indicates the basic curves of change of the parameters.
