All-UWB SLAM Using UWB Radar and UWB AOA
IEEE Robotics and Automation LettersThere has been a growing interest in autonomous systems designed to operate in adverse conditions (e.g. smoke, dust), where the visible light spectrum fails. In this context, Ultra-wideband (UWB) radar is capable of penetrating through such challenging environmental conditions due to the lower frequency components within its broad bandwidth. Therefore,

IEICE Transactions on Communications, 2010 Recently, microwave ultra-wideband (UWB) technology has attracted much attention in high speed wireless communications, imaging and radar applications. Antennas with very wide impedance bandwidth and stable radiations are required for such systems. Among many UWB antennas, planar types are low profile, light weight, low cost and suitable for mobile ...
