Effect of Stolt f-k migration filters on ground penetrating radar imaging

Abstract

Background: Some filters such as (Stolt F-K Migration) and complimentary filters (Time –Zero Adjustment,
Background Removal, and Band –Pass) are used to study the effectiveness, digital filters, and to enhance the quality
of radar grams. This filter considered one of the advanced processing filters in general. Materials and Methods:
Ground Penetrating Radar (GPR) is a device that transmits short pulses of electromagnetic energy with pulse duration
about 1 ns to 20 ns with a high-frequency range from 10 MHz to 1000 MHz in the ground by a transmitting antenna.
The input analogue signals digitized and quantified using an analogue-to-digital the converter in order to be ready for
processing in the computer to create images called the radar gram. Results: The important feature focused on making
visible the weak signals and improves certain components required to interpret the data. Conclusions: Applying Stolt
F-K Migration filter on profile GPR cretaceous limestone rock detected at a depth of 3.75m. Whereas, applying the
filter to the same profile of water pipe at a depth (0.632m)near the road for the faculty of pharmacy at the direction
from north to south. When applying the filter) to the same profile of difference in the thickness of pavement layers
which consist of a foundation layer and a layer of asphalt.
