Theoretical modeling of the station displacements produced by tidal de
formations of the Earth due to lunisolar gravitational forces is a nec
essary part of the analysis of space geodetic data. To attain the accu
racies demanded by the precision of the data, a generalized version of
the Love number formalism has to be used wherein the classical Love a
nd Shida numbers are replaced by sets of Love number parameters with v
alues that depend on the frequency of the tidal excitation. This paper
presents theoretical expressions for the contributions from the vario
us Love number parameters to the station displacement vector and a sch
eme for efficient computation of these contributions, taking into acco
unt the frequency dependence of these parameters as well as the imagin
ary parts that are present when the effects of mantle anelasticity are
taken into account. A brief discussion of the permanent tide which ar
ises from the zero frequency component of the tide-generating potentia
l is included.
