| Abstract: | Aiming at the problem of time delay estimation for buried target echo in ground penetrating radar (GPR) system, the essential preprocessing steps for the application of the estimation of signal parameters via rotational invariance technique (ESPRIT) to GPR time delay estimation are described in this paper in detail. In particular, a superresolution time delay estimation algorithm using ESPRIT based on improved spatial smoothing (ISS) method is proposed in this paper. The simulation data generated by finite difference time domain (FDTD) method using layer model have verified the validity and reliability of the proposed algorithm. |
