Abstract :
For the tracking of moving target in through-wall-radar imaging, the trajectory accuracy depends on the accuracy of the extracted target position. In the case of multiple targets, it is difficult to extract the faint target information and separate the adjacent targets effectively. To deal with these problems, the paper presents a target extraction algorithm based on multiple thresholds. The target positions are extracted and sequenced according to their peaks after finding the connected domains of the same target in each threshold. The simulation results validate the algorithm.
