Abstract
The earth tidal tilt data consists of two parts: one is
the theoretical part caused by the tidal potential of the
moon and the sun; another one is the seismic noise part that
originates from meteorological, hydrodynamic , and cultural
sources. The theoretical part is completely determinable
by astronomical data. The seismic noise may be considered
as a stationary stochastic process over short periods of
time when there have been no great changes in the source
mechanisms. Based on the above assumption, prediction and
interpolation of the earth tidal tilt data can be achieved
by solving the Wiener-Hopf equation. A computer program
"PREDICT" is derived by using Levinson's recursive method to
solve the discrete-time Wiener-Hopf equation. Test results
on real data are satisfactory. Besides the earth tidal tilt
data, the "PREDICT" program can also be applied to any
stationary stochastic discrete-time signal.
