This paper focuses on the affection of the curved surface media. In order to study it, the continuous wave penetrating radar (CWPR) is applied to detect targets buried in the spherical media. The antennae move in a plane above the spherical surface and execute two dimensions sampling. Different from planar media, this special geometry makes the echoes of the surface interfere, and several circular...
Ultra-wideband (UWB) pulse generators based on an avalanche transistor are widely used in time domain ground penetrating radar(GPR). For shallow subsurface detection, it is essential to increase the pulse amplitude while maintaining the pulse width in order to improve the spatial resolution of GPR. Eliminating pulse trailing is also necessary to improve GPR performance. In this paper, a simple nanosecond...
An adaptive linear neuron network is employed for reversing the location and back scattering density of objects from ground penetrating radar data. The processing avoids the disadvantage of unknown electromagnetic velocity in a medium for the specific rebar detecting application. Based on the common-offset reflection GPR survey model, the network was derived by reconstructing and compressing the reflected...
