摘　　要：针对多传感抗差航迹关联问题,从理论上分析传感器系统偏差对航迹点集拓扑结构的影响,利用非刚性变换表征两点集之间的拓扑差异.建立抗差航迹关联问题的点模式匹配模型,采用基于松弛标号迭代的非刚性点匹配方法对其进行求解.针对不同测距、测角偏差、目标密度和检测概率水平构造多组典型仿真场景,仿真实验验证了所提出算法的有效性.The problem of anti-biases track-to-track association is addressed. The theoretical analysis is given concerning how the topology structure of the point set formed by multi-target tracks is affected by sensor biases, and the topology difference between two point sets is represented by the non-rigid transformation. A point matching model for anti-biases track-to-track association is established, and a relaxation labeling based non-rigid point matching algorithm is proposed. Performance comparisons are implemented in terms of various typical simulation scenarios, such as different range biases, angle biases, target intensities and detection probabilities. Simulation experiments are conducted to verify the superiority of the proposed approach compared to other competing algorithms.
