UWB pulse radar systems are promising candidates for a high range resolution imaging in a near field. We have already proposed rapid and robust imaging algorithm with envelope of spheres. It can realize stable 3-D imaging for an arbitrary target shape without derivative operations. However, the estimated image with this method is distorted especially around the target edges and wedges due to waveform deformations. In this paper, we propose fast and high-resolution 3-D imaging algorithm by

The application examples with numerical simulations and an experiment verify that the proposed method accomplishes highspeed, accurate 3-D imaging, including target edges, with the order of 1/100 center wavelength of the UWB pulse.
