针对封闭空间建筑物透视雷达运动目标的跟踪问题,基于穿透式寿命探测雷达,深入研究人体运动轨迹的探测,从而构建可以实现人体运动目标模型的协方差矩阵及状态转移矩阵,使用邻域简化联合概率数据互联方法解决点迹争夺及航迹分叉等问题,可以避免产生虚假航迹的现象。将Matlab仿真验证算法应用在机动目标、简单运动单目标以及多目标中;对外场实测数据进行采集并处理,在多层墙体穿透、单目标以及多目标中都获得良好的效果,可滤除虚假杂波点,将目标运动轨迹准确标出。

Aiming at the problem of moving target tracking of perspective radar for closed space buildings, based on penetrating life detection radar, the detection of human motion trajectory is studied, and the covariance matrix and state transition matrix suitable for the corresponding motion model of human moving target are constructed, plot contention and track bifurcation are solved by the joint probabilistic data interconnection which is simplified by the nearest neighborhood. The method of track management can effectively reduce the false track. In the simulation, Matlab is used in maneuvering target, simple moving single target and multi-target; the field measured data are collected and processed, and good results are obtained in multi-layer wall penetration, single target and multi-target, which can filter out false clutter points and mark the target trajectory correctly.
