Kirchhoff and F-K migration to focus ground penetrating radar images

Abstract

Ground penetrating radar (GPR) based land mine detection has a main challenge of having an accurate image analysis method that is capable of reducing false alarms. However this image analysis depends on having sufficient spatial resolution in the backscattered signal. This paper aims at getting better resolution by applying two migration algorithms. One is by Kirchhoff’s migration using geometrical approach and other one is F-K migration algorithms with Fourier transform. The algorithms are developed using MATLAB simulations over different scenarios for stepped frequency continuous wave (SFCW) GPR.
