Abstract :
In this paper, experimental investigation has been performed in order to compare the performance of different migration algorithms for short-range imaging. These algorithms include diffraction stack, Kirchhoff migration, and range migration algorithm (FK migration). Their resolution, beam pattern, ability for shape reconstruction, and computational complexity are compared and analyzed. The data processing schemes are described and illustrated using both numerical simulation and measurement data set. The resulting comparison provides guideline in terms of choosing suitable image processing method for practical applications.
