摘要
在雷达、红外等传感器的目标航迹起始时,目标的机动性以及数据的批处理会导致目标运动轨迹上偏离点的漏检。针对该问题,首先在Hough变换基础上,根据目标运动速度、幅度等信息置信区间与杂波干扰的不同,加上权重因子进行累积,然后进行目标的航迹起始,最后利用蚁群相似度检测起始轨迹上的偏离点迹。仿真结果表明,较之传统Hough变换,采用加权Hough变换算法能有效检测到目标航迹上的偏离点迹,提高目标检测概率。
In track initiation based on radar,infrared sensor and etc,the mobility of target and batch processing ofdata lead to failure in detection of part of the deviate points on straight trajectory. This paper proposed an improvedweighted Hough Transform based on ant colony similarity algorithm for track initiation to deal with the aforemen-tioned matter. According to the various confidence interval of moving target information,which is different from theclutter interference,the proposed method adds weighting factor in basis of traditional Hough Transform and accumu-lates. Ant colony similarity is employed to detect deviate points of target trajectory. The results of simulation indi-cate that weighted Hough Transform improves detection probability. Comparing with traditional Hough Transform,the proposed method more effectively detects the deviation target points in trajectories.
