Embodiment Construction
[0059] Specific embodiments of the present invention are further described in detail below.
[0060] For the spherical integrable function f(θ,λ), it can be expanded into an infinite series of spherical harmonic functions, that is, a spherical two-dimensional generalized Fourier series. Its expression is
[0061]
[0062] In the formula is the surface spherical harmonic coefficient, is the normalized Legendre function, θ, λ are the co-latitude and longitude respectively, n, m are the order and order of the spherical harmonic coefficients respectively.
[0063]When the given f(θ,λ) is the specific earth disturbance gravitational observation data, the formula
