In this work, performance of a novel two-parameter method of microwave subsurface visualization has been studied with the use of experimental data. The method is based on building the image of subsurface area in which the amplitude data govern intensity of the pixels whereas their color is associated with phase information. The phase is understood here as the phase shift related to the reflection...
This paper presents a signal pre-processing technique for the stepped-frequency ground penetrating radar that is aimed at suppressing clutter related to antenna effects and variation of the ground surface response. Both the ground bounce and the clutter can obscure shallow underground objects such as landmines making difficult their detection. At the preprocessing stage, the measurement system has...
A new microwave imaging technique forming the 2-D image from a set of one-dimensional dielectric profiles is proposed. To obtain the 2-D subsurface image, the backscatter data is collected along a line over the tested medium and processed by a conventional synthetic imaging method as done in the synthetic aperture radar (SAR). In this work, every radar range profile is first transformed to one-dimensional...
