摘要
介绍一种改进的固定增益卡尔曼滤波方法。这种方法的思想是采用多个固定的滤波增益并根据机动的情况在各个增益之间切换。同时提出了一种将距离变化率量测引入固定增益卡尔曼滤波的方法。由于不需要实时的计算卡尔曼滤波的增益矩阵,此方法大大的降低了运算量,并仍能保证较高的滤波精度。
This thesis concentrates on the method of improved fixed--gain Kalman filter. The idea of this method is using several fixed gain of filter and switching between them based on the condition of motions. On the other hand, an algorithm is developed to incorporate range rate measurement into fixed-gain Kalman filter. Since the calculation of the matrix of Kalmann filter gain is not necessary, this method does not only reduce the cost of computation, but also ensure a good filter precision.
