Ultra-wide band pulse radar has a higher range resolution. It is promising as a near field sensor for rescue robots or security systems, where an accurate 3-dimensional measurement impervious to optical environments is indispensable. However, in typical indoor sensing situations, aperture size is severely limited by obstacles such as collapsed furniture. The available radar image is then too narrow...
Ultra-wide band (UWB) pulse radar has a definite advantage over optical ranging techniques, as to applicability to the harsh optical environment, such as the dark smog, or strong back-light. We have already proposed the extended Synthetic Aperture Radar (SAR) algorithm employing the multiple scattered waves, which aims at enhancing the reconstructible region of the target boundary including the shadow...
