摘　　要：为实现舰载雷达与红外传感器航迹正确关联,提出了基于最优航迹隶属度的雷达与红外航迹关联方法。首先以角度信息作为量测数据,进行航迹间统计距离的运算,而后构建方位角、俯仰角隶属度矩阵以及分辨率隶属度向量,以分辨率隶属度向量作为判决门限并结合最大隶属度原则共同对航迹关联与否执行判决。仿真实验表明,基于最优航迹隶属度的方法在雷达与红外航迹关联应用中性能明显优于最近邻法与加权航迹关联法,在目标密集和传感器量测误差较大时略优于模糊综合函数法,但性能更为稳定,正确关联概率在75%以上。In order to realize the correct track correlation between radar and infrared sensor,a method for the track correlation based on the optimal track membership is proposed.Firstly,the angle information is taken as the measurement data to calculate the statistical distance between the tracks,and then the membership matrix of azimuth angle and pitch angle,and the resolution membership vector are constructed.The resolution membership vector is taken as the decision threshold and the maximum membership principle is adopted to execute the judgment on whether the tracks are correlated or not.The simulation results show that,the performance of the method based on the optimal track membership is obviously better than that of the nearest neighbor method and the weighted track association method in the application of the track association of radar and infrared sensor.Under the conditions with high target density and large sensor measurement error,it is slightly better than the fuzzy comprehensive function method,but the performance is more stable,with a correct correlation probability above 75%.
