A method for filtering in ranging of a UAV is provided, which is based on a characteristic that velocities of the UAV change continuously during a moving process. A current velocity of the UAV is obtained via seeking difference of distances measured by the sensor, then a variance of continuous velocities is calculated and it is determined whether a current distance is valid according to the variance. The general process of the method is as follows. First, initial distances measured by the sonar sensor are acquired, secondly, it is determined whether a new distance is valid according to the initial distances, if the new distance satisfies a curtain condition, the new distance is considered to be valid and the initial distances are updated; if the new distance does not satisfy the curtain condition, a distance is estimated and used as the current distance and the initial distances are maintained.
