摘要:

针对随机恒速运动目标条件下已知的目标初始位置分布密度和速度分布密度,建立了时变的运动目标分布密度模型和在离散时间点上实施有限区域探测后的目标分布密度模型。以此为基础,提出了依次探测的单次探测发现概率最大的最优搜索准则,计算在该准则下的离散时间点上有限探测域的最优探测位置。最后,给出了一个二维空间搜索算例。

Abstract:

Based on the probability density functions of initial location and moving velocity of a constant velocity target, the probability density function of the target at any time and after the limited area detection in discrete time are presented. The optimal detection areas in discrete time are obtained through the calculation with the given criterion of maximum detection probability of every detection round. A 2-dimension calculation sample is given.
