Abstract：Considering the characteristics of the processing of aerial gravimetry data, a FIR digital filter based on the window function is designed. The results show that FIR digital filter has accurate linearity phase and its filtering process is steady and the method is simple and easy to be realized on the computer.The barrier phenomena in the Fourier transform can be partially reduced by the convolution integral in the process of filtering.
