Abstract

On the premise that the system is a linear time-varying model, this paper describes a ground-penetrating radar (GPR) deconvolution technology based on a formation spectrum compensation factor The formation spectrum correction factor in the fractional Fourier transform domain is determined using an optimal filtering algorithm. This verifies the original records of the spectrum using the correction factor in the transform domain, and improves the resolution of the GPR data. The algorithm proposed in this paper is validated using a simulation model data. Its performance is then compared with that of a conventional GPR deconvolution algorithm. The results verify that the proposed algorithm is more reasonable and effective than the traditional method.
