APPLICATION OF FAST FOURIER TRANSFORMATION IN MEASURING SATELLITE GRAVITY GRADIENT

Liu Shangyu Zhou Fang (Guangzhou Satellite Observation Station,Academia Sinica)  
Complex_base fast Fourier transformation(FFT) is used in data_processing of satellite gravity gradients in this paper.Also carried out are the numerical simulation calculations of gravity gradients from potential coefficients,and of potential coefficients from global gravity gradients.The numerical results show that,with the introduction of FFT,the computational speed is greatly raised,which is raised even more greatly with the increase in the number of the degree n .When n =50,this peed increases 10 times,and n =120,30 times or more.
