We tested an off-ground ground-penetrating radar (GPR) system at a fixed location over a bare agricultural field to monitor the soil freeze-thaw cycles over a snow-covered surface. The GPR system consisted of a monostatic horn antenna combined with a vector network analyzer, providing an ultra-wideband stepped-frequency continuous-wave radar. An antenna calibration experiment was performed to f...
routing metrics and algorithm for the future system are detailed.
Ultra wideband (UWB) radio is a new wireless technology that uses sub-nanosecond pulses to transmit information, resulting in a bandwidth greater than 1 GHz. The problem of synchronizing a receiver with the incoming signal grows in complexity as the signal bandwidth increases. This paper addresses coarse synchronization in UWB receivers. It analyzes how the design of the correlation process aff...
In this paper, we propose a distance estimation scheme for radar systems using direct sequence ultra wideband (DS-UWB) signals. The proposed distance estimation scheme averages out the noise by accumulating the correlator outputs of the radar, and thus, helps the radar to employ a short-length DS-UWB signal reducing the correlation processing time. Numerical results confirm that the proposed di...
