Handheld ground-penetrating radar (GPR) system is one of a number of technologies that has been researched as a means of improving landmine detection efficiency. However, as the measurement points are random and data are irregular for the human operator, it is difficult to display subsurface visualization imaging. Also detection of buried landmines by GPR normally suffers from very strong clutter...
There have hand-held GPR systems and vehicle-mounted GPR systems, which are offset from the air-ground interface by a nonnegligible distance, developed for landmine detection. Vehicle-mounted systems have exclusive advantage that can show subsurface imaging in horizontal slices based on grid GPR data set. Hand-held GPR system is one of advantageous technologies in mountain district etc. But handheld...
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...
