Abstract :
This paper addresses an effective approach for image reconstruction. An ultra-wideband (UWB) signal is transmitted from an element of an antenna array. Backscattered waveforms collected at each antenna are then processed in frequency domain. Their energy is computed and imaged as a function of location. Simulation results show that localized regions of high energy levels in the image consistently correspond to the object present in the simulation space.
