此方法不需要目标机动的先验知识，而是构造一个可自适应调整的缩放因子，通过该因子对过程噪声进行调节。

This approach does not rely on the prior knowledge to the target motion, and utilizes a zoom factor, which can adjust itself adaptively. By this factor, the process noise covariance can be modified.

The approach did not rely on prior knowledge about the target motion, and utilized the expectation of the sum of squares of "new value" to construct a zoom factor, which can adjust adaptively.
