N2 - Migration technology is originated from seismic imaging field and has been widely used in ground penetrating radar signal processing. In this paper, the theories of four migration algorithms are studied and an interpolation method in time-frequency domain is proposed to enhance the image resolution of F-K algorithm. Based on the parameters of computational complexity, resolution, sidelobe level and dip-angle range, numerical simulations are carried out to investigate and compare the target reconstruction performance of these algorithms. By comparing the migration results of point-like target, distributed target and tilt target, some valuable conclusions about these algorithms are obtained, which will provide a guidance for selecting specific migration algorithm in practical engineering applications.
