چکیده
In this paper, we present the feasibility of applying UWB radar signal to material characterization and distance measurement. Distance detection by using dynamic energy visualization method was presented and showed good agreement. This technique might be useful for searching and rescuing humans in disaster sites.

متن کاملA Compressive Sensing Signal Detection for Uwb Radar
A major challenge in UWB signal processing is the requirement for very high sampling rate under Shannon-Nyquist sampling theorem which exceeds the current ADC capacity. Radar signal is essentially a delayed and scaled version of the transmitted pulse, determined by sparse parameters such as time delays and amplitudes. A system for sampling UWB radar signal at an ultralow sampling rate based on ...
