faxian gail位发现概率(deteetion probabili‘y)某种探测设备发现预定目标可能性大小的量度。亦称探测概率或检测概率。探测是由一系列间隔的“瞥”或连续的“凝视”组成。若记一“瞥”的发现概率为g，第i次“瞥”的发现概率为gi，_巨各次“瞥”互相独立，则总共n次“瞥”的发现概率为: 只=1一(1一乌)(1一乳)…(1一又)若记在时间微元dt内“凝视”的发现概率为:(t)dt，其中:(t)表示瞬时发现概率，则在适当条件下，总共探测持续时间T的发现概率为: 尸(:卜卜exp[一叮于(才)d才1实际上，瞬时发现概率不仅可以是探测时间t的函数:(t)，同时还可以是目标位置x的函数，即可表述为;(x，t)，则对目标位置x总共探测持续时间TI狗发现概率为: 。x，:卜卜exp卜刃’:(二，扩)drl (凌如镐)
