| 摘 要： | 首先分析了STLFMCW雷达估计目标径向运动速度的原理。针对利用频谱特征进行目标配对求取速度方法存在的缺陷,将多目标跟踪技术应用于目标配对,分别对上、下扫频段多目标回波起始"局部航迹",在"局部航迹"正确起始后,利用同一目标上、下扫频段内"局部航迹"的相关性实现了多目标配对;并通过配对确认矩阵的拆分减小了配对的多义性,从而显著提高了目标正确配对的概率。仿真结果表明,在复杂多目标与杂波环境下,该方法能有效实现上、下扫频段目标回波的正确配对。

| Abstract: | The principle of target radial velocity estimation in STLFMCW radar is analyzed. To overcome the defect of target pairing methods by matching spectrum characteristics,a multi-target tracking technique is adopted to initialize "local tracks",and a novel multi-target pairing algorithm based on track correlation is proposed.Then,a ambiguity elimination pairing method by decomposition of the pairing indication matrix is presented to improve the pairing performance significantly.Finally,the validity and feasibility of this algorithm in multi-target circumstance is verified by simulation. |
