The Study of Signal Processing Performance for Simulation Radar Signals for Drone-Carrying Ground Penetrating Radar
In this research, a B-scan image simulation method of a ground-penetrating radar mounted on a drone (GPR-drone) by using high-frequency technique is proposed. The proposed simulation method aims to predict GPR-drone receiving signals in a complex three-dimensional (3D) scenario. This research employed the TD uniform geometrical theory of diffraction (UTD) method including the geometrical optic (GO) rays tracing technique to find the GPR reflected signal from the ground layer and the underground object. The diffracted ray path of a monostatic GPR is also calculated. The fast Fourier transforms (FFT) method is employed to find the TD-GPR signal. Three dimensional (3D) locations of a drone are considered. The calculated results found that the proposed procedure can be used to predict the GPR mounted on a drone signal .
