摘　　要：在现行的机动目标跟踪过程中,由于目标真实的运动过程是不确定的,一般需要根据目标运动规律的假定,人为地给出目标的预置模型,因而精度难以提高。针对这一问题,引入参数辨识模型,既可对参数动态地进行识别而无需进行模型的预置,又具有对工作周期变化的适应能力,可以覆盖机动目标可能的多种运动状态,使自适应滤波问题可在正常的技术思路下进行。运用Matlab语言建立仿真模型,通过四种典型运动对该算法进行了验证,结果表明此方法正确可行。In the existing process of maneuvering target tracking, the target＇s actual moving model is unknown, so a preset supposed model should be given, but it is difficult to improve the precision. Concerning the problem of ma- neuvering target tracking, a parameter identification model is presented, which identifies the target＇s model dynamically, has the ability of adapting to the variation of working cycle, and covers kinds of possible moving states of maneuvering target, thus making adaptive filtering go on normally. Then the Matlab language is used to construct simulation models to test the algorithm through four typical movements and the results show that the method is right and feasible.
