摘要/Abstract

摘要： 针对传统关联波门设计方法在应用于机动目标跟踪时容易引起失跟、以及概率数据关联算法不适于多交叉目标跟踪的问题，提出了一种基于人类视觉选择性注意机制和知觉客体的"特征整合"理论的认知雷达数据关联算法。算法以综合交互式多模型概率数据关联算法为基础，采取假设目标最大机动水平已知的"当前"统计模型和匀速运动模型作为模型集，通过实时交互使关联波门能够随目标机动动态调整，较好地兼顾了雷达计算耗时和跟踪成功率。在利用目标位置特征的基础上，进一步提取、整合目标运动特征，对关联波门交叉区域公共量测进行分类，使多交叉目标跟踪问题转化为多个单目标跟踪问题，优化了传统概率数据关联算法。仿真结果表明：与传统关联波门设计方法相比，算法跟踪失败率和计算耗时明显降低；而且在计算资源增加不大的情况下，杂波环境适应性也得到了显著增强。

Abstract: Maneuvering target tracking loss often occurs with the traditional association gate design method, and the probabilistic data association algorithm is not fit for multi-cross target tracking. To overcome these problems, a cognitive radar data association algorithm is proposed based on the human visual attention model and the perceptual object "feature integration" theory. The algorithm is based on the comprehensive interacting multiple model probabilistic data association algorithm, and uses the "current" statistical model, in which the maximum maneuvering level is known, and the uniform motion model as the model set. The association gate can be adjusted via target maneuvering, balancing the radar computing time and tracking success rate. Based on the features of target location, the motion features of the target are extracted and integrated to classify the public measure in the cross area of the association gate. The multi-cross target tracking problem is then transferred into the problem of tracking of multiple single targets, so the traditional probabilistic data association algorithm is optimized. Simulation results show that the proposed algorithm can significantly reduce the tracking failure rate and computing time, and the optimized data association algorithm with slightly more time consumption is more environment adaptable than the traditional algorithm.
