An Interpolation Decoupling Method of Multi-Sensor Information Based on Variance
In order to solve decoupling problem of homogeneous multi-sensor information which couples with other sensor’s information, the paper proposed an interpolation decoupling method of multi-sensor information based on variance; based on multi-scale approximation principle, it used a interpolation decoupling method to calculate scale threshold under a prediction precision target, and realized information decoupling; in the decoupling process, it adjusted the scale threshold by actual change of decoupling variance. Emulation results shows the decoupling variance decreases 13.56% by using the online adjustment method of scale threshold, after decoupling and fusion of multi-sensor information, the measurement precision increases 2.02 times as much as a single sensor, the interpolation decoupling method based on variance has high precision and good real-time characteristic.
