摘要
随着雷达技术的不断成熟,雷达跟踪领域涌现出了大量的跟踪算法,目前,交互式多模型算法凭借其精准的跟踪能力和优越的性能已逐步代替其他的目标跟踪方法被广泛应用到雷达航迹跟踪的各个领域。通过对IMM算法的研究发现建立IMM的CV、CA、CT运动模型并结合使用扩展卡尔曼滤波可以有效提高跟踪精度。基于MATLAB实验仿真表明改进后的IMM算法能以较高精度输出被跟踪目标的状态信息,取得了良好的跟踪效果。
With the continuous maturity of radar technology,a large number of tracking algorithms have emerged in the field of radar tracking.At present,the interacting multiple model algorithm has been widely applied in various fields of radar track tracking by virtue of its accurate tracking ability and superior performance,which has gradually replaced other target tracking methods.Through the study of IMM algorithm,it is found that the establishment of CV,CA and CT motion models of IMM and the combination of extended Kalman filter can effectively improve the tracking accuracy.Experimental simulation based on MATLAB shows that the improved IMM algorithm can output the state information of the tracked target with high precision and achieve good tracking effect.
