Abstract
Combining SAR imaging technique with a UWB radar sensor can realize high resolution imaging of targets. It has important research value in environment investigation and inter surveillance. In this paper, three dimensional SAR imaging is investigated based on the one dimensional echo signal of UWB at different locations and time. The UWB SAR image reconstruction is realized by Hamming window function optimization, image registration and interpolation. The reconstruction imaging of the metal ball with centimeter resolution is realized, which verifies the feasibility of the imaging system in this research for 3D SAR imaging.
