英文摘要

      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.
