| 摘 要： | 针对二维机动目标跟踪的波形选择问题,将传统正交自适应波形选择法进行扩展。该波形选择方法以IMM-EKF作为基础跟踪算法,将IMM-EKF输出的预测协方差对应的椭球投影到r-r觶平面上,选择量测误差椭圆与投影椭圆正交的发射波形。仿真结果表明,该算法可以有效改善目标跟踪精度,并讨论了参数选择对正交法改善跟踪系统精度的影响。

| Abstract: | The conventional adaptive waveform selection based on orthogonal covariance is extended to the two dimensional target tracking with adaptive waveform.It is based on IMM-EKF tracking algorithm,where the ellipsoid corresponding to the prediction state covariance of IMM-EKF is projected to the r-plane,the best waveform whose measurement error ellipse is perpendicular to the projection ellipse is chosen correspondingly.Simulation results show that the waveform selection can improve the tracking performance effectively.Furthermore,the effect of parameter setting to tracking performance is discussed. |
