Over the last three decades, ultrawideband (UWB) radars have been designed for military and civilian applications, such as ground-penetrating radar for detecting and imaging antipersonnel and antivehicular mines, sensing through canopies for opposing forces, identifying combatants and weapons in structures, and mitigating targetlike structures induced by sea scatter for sea-based radars. In addition, numerous nonmilitary UWB radars have been designed and fielded for forestry, detecting underground utilities, automotive control, search-and-rescue operations, and humanitarian demining. Since 2004, UWB radar development has declined somewhat to a plateau, with most efforts concentrating on medical imaging, automotive control, sensing through structures for terrorists, and search and rescue operations. In contrast, UWB communication systems have come to the forefront on the wave of the telecommunication revolution. The main reasons for using UWB radar are its competing capabilities of imaging objects due to its ultra-high resolution (higher frequencies) and penetrating media to detect shielded objects (lower frequencies). For example, a design of UWB radar is a tradeoff between resolution and penetration depth. Thus, the passband selection of the radar depends on the application, i.e., on the dimensions of the objects of interest. Although ultrahigh range resolution and deeper penetration are desirable, UWB radar has technological and electromagnetic-compatibility (EMC) issues. The appeal of UWB communication is that voice and data transmissions
