摘要: 对非线性系统的状态估计通常采用推广卡尔曼滤波,但由于此方法计算量大、往往在实际工程中不能实时处理,为此,对推广卡尔曼滤波提出了不少简化方法。如解耦滤波及改进α-β-γ滤波等(参见[2])。
本文提出的方法将系统进一步简化为满足稳态滤波条件的定常系统,计算量大大减少;经实际模拟计算,滤波精度可达相当高的水平。
该方法可用于地面电影经纬仪或雷达对飞行目标的自动限综。

Abstract: This paper presents a simplified nonlinear filtering-direct compensation and dimension raising.
Using this method, the original system will be simplified by a higher order polynomial dynamic model and realize transition matrix constancy. So the computation will be very simple.
Specially, it is suitable for the problems of the real time treatment.
After thorough the simulant compute, its effect achieves good results.
We can apply this method to filming theodolite or radar for automatic tracking of the flying target.
