| 摘 要： | 将Kalman预测方法用于经纬仪跟踪机动目标，对不同靶标旋转速度下的目标跟踪进行了仿真研究。提出了状态方程输入矩阵G(k)，并在实际测试计算中验证了G(k)的正确性。根据Kalman预测曲线与实测曲线误差的标准方差最小原则，确定了状态噪声与测试噪声的方差比值Q／R，并确定了适合经纬仪的比值Q／R。仿真结果表明：Kalman预测方法可以很好地完成经纬仪跟踪机动目标的仿真。

| Abstract: | Kalman prediction method was applied to theodolite's tracking mobile target, and simulation research of tracking mobile target was conducted under different target beacon velocity. Input matrix of state equation G(k) was presented, and correctness of G(k) was confirmed in practical test and calculation. According to a principle of least standard deviation of Kalman prediction curve and practical curve, the deviation ratio of state noise and test noise Q/R was defined, and the ratio Q/R for theodolite was defined. The simulating results show that Kalman prediction method can be applied to theodolite's tracking mobile target simulatioion satisfactorily. |
