As for the conventional ground penetrating radar (GPR) system, the detection result is seriously affected by the antenna directionality, the target scattering sections (RCS) and multi-polarization characteristics of electromagnetic wave. The MIMO (Multiple-Input and Multiple-Output) array antenna GPR technology can overcome the influence of RCS, electromagnetic polarization and improve the quality...
The ultra wideband (UWB) radar has greater advantage in estimate positions and shapes of the target in Through Wall Imaging (TWI). One significant characteristic of human beings is the periodic motion, such as respiration and movement of arms. In this paper, we apply the UWB pulse radar to detect the periodic motion in through-wall detection. We present methods based on the FFT and time-frequency...
