This research aimed to study the lengths effect of calculated filter- operator
by inverse filtering on the seismic data filtering. All programs used for
estimating the seismic signal, calculate the Filter- operator and performing the
Convolution w

Some experiences about the influence of the length of filter-operator of the
outcomes of the inverse filtering were performed. The seismic data used in this
research were measured in two different areas in Syria, Alsaegh dam nearby
Sueda City and Rajo dam nearby Aleppo City. In addition, experiences are
carried out to test the effect of shortening the length of filter-operator.
The results showed that small length of filter-operators can be used by
inverse filtering without negative effect on the resolution of seismogram. In
addition we noticed that shortening the length of filter-operator depend on the
length of calculated filter-operator.
This research aimed to use the homomorphic deconvolution, applied for
processing seismologic and seismic Data, for processing the georadar Data. To
reach this aim, some changes in the algorithm of signal determination have
been carried out, in ord
er to match the properties of georadar data, I wrote a
computer Program, that include several steps, starting from transforming and
reading the field data, and ending by performing the inverse filtering.
The research shows the importance of the homomorphic deconvolution to
improve the resolution of Georadar-Record by raising the frequency content on
the field – georadar data. Using various field data measured at various
Locations by different Instruments, to test this method of deconvolution. The
results shows the efficiency of this method in differentiation the image of
georadar-Record, and consequently help the interpretation, which maximize
the applicability of the georadar data.
