| 摘 要： | 主要研究杂波密集环境下多目标航迹起始问题,提出一种改进Hough变换和最小方差准则相结合的航迹起始方法.首先针对航迹起始中量测信息的时间特性,提出一种改进的积累单元积累方式,该方法较以前的二值积累方式能更有效地去除杂波,尤其能够去除构成虚假航迹的杂波.然后,再采用最小方差准则对Hough变换之后的航迹进行分析,得出正确的航迹.仿真结果表明,提出的航迹起始方法效果好、所用时间短,尤其适合杂波密集环境下的快速航迹起始.

| Abstract: | The track initiation of multi-target in dense noisy environment is concerned A method combined improved Hough transform and least-square criterion is proposed.Firstly,an improved accumulation method of accumulation cell is proposed according to the measurement information coming from different time.The proposed method deletes the noise more accurately than the conventional method,especially the noise composed of false track.Secondly,the tracks are analyzed by least-square criterion and the right tracks are ... |
