An Improved Adaptive Kalman Filter for Gravity Anomaly Distortion Correction

摘要：

　　Combined with the system state equation and the measurement equation,a new method of cascade Kalman filter is proposed and applied to the correction of gravity anomaly distortion.In the signal processing procedure,according to the self-correlation sequences of the measurement gravity signal,the relation of the gain matrix K and the self-correlation sequences could be obtain,and the gravity signal at current time can be calculated by the gain matrix K.Emulations and experiments indicate that both the cascade Kalman filter method and the single inverse Kalman filter method are effective in alleviating the distortion of the gravity anomaly signal,but the performance of the cascade Kalman filter method is better than that of single inverse Kalman filter method.
