摘要
为了满足车载雷达对地目标探测中,由于强地杂波的影响而导致的虚假航迹多的缺陷,通过对目前航迹起始方法的分析,针对传统逻辑航迹起始方法的改进,提出了应用于强地杂波环境中,极坐标系下的航迹起始方法,并通过仿真证明,本方法与逻辑起始方法在航迹起始方面具有相当的航迹起始概率,但是在地杂波比较严重时,虚假航迹的数量大幅减少,是一种理想的强地杂波环境中对地目标跟踪的航迹起始方法。
When vehicular radar is detecting ground targets, heavy ground clutter may lead to more false target tracks. Through analyzing track initiation methods used currently, a polar coordinate system-based track initializa- tion algorithm which is suitable for ground target detection in heavy ground clutter scenario is proposed based on im- provement of logical track initiation algorithm. Simulation result verified that, comparing with the logical track initi- ation algorithm, track initiation probabilities of these two improved method is reduced significantly in heavy clutter initiation method which is more suitable for heavy ground method are comparative, but false tracks quantity of this circumstance, therefore it is a perfect ground target track clutter condition.
