Using FIR (Finite Impulse Response) lowpass digital filters based on window functions, the authors conducted experimental researches on the filtering of airborne gravity data, and obtained some useful results. By selecting proper window shape, window length and filter parameters, the window functions FIR lowpass digital filters can attain a good filtering effect on airborne gravity data.
