摘要 为了更好地跟踪机动目标 ,提出了一种机动目标跟踪的改进方法 .利用目标的跟踪残差 ,求取跟踪滤波器的理论残差方差值 ,再根据统计的残差方差 ,建立了残差的假设检验阀值 .并对其算法进行了具体的推导 ,得出自适应选择机动频率的原则 ,使机动频率与目标的当前状态更接近 .对“当前”模型和改进后的模型进行了仿真 ,仿真结果表明该方法具有更小的跟踪误差 。 To track a maneuvering object,an improved method of tracking a maneuvering object was advanced.Based on the tracking residuals of object,the theory residuals self-covariance was gained,and the supposed testing value of residuals was gained,which utilized the statistical residuals self-covariance.The rule of adaptively choosing maneuvering frequency was educed by careful deducing arithmeticly,so that the maneuvering frequency could be close to the true state of object.By simulating on the current model and the improved model,the test results indicate that the improved model has smaller tracking error,which verifies the efficiency of the model.
