| 摘 要： | 在PD雷达检测中,雷达接收到的回波信号的能量相当弱时,用传统的雷达积累与检测方法不能可靠地检测目标.检测前跟踪技术(TBD)是一种多帧信号积累技术,其基本思想是对多帧信号进行处理,先进行目标预测,在此基础上对检测出的目标进行目标跟踪,利用目标的运动特征沿各种可能轨迹积累能量.然后对各个能量积累值进行检测判断,从而检测出真实目标,同时提取出目标的轨迹.研究了一种动态规划应用于雷达小目标检测的方法.

| Abstract: | In the PD radar detection,when the echo signal energy received is quite weak,the targets cannot be detected reliably with the traditional radar accumulation and detection method.The track-before-detect technology (TBD) is a multi-frame integration technology,its basic thought is a multi-frame signal processing.At first, the target prediction is carried on,and then targets are tracked in this foundation,accumulating the energy according to the target movement characteristic along each possible path.Then the ... |
