TL;DR: A high-resolution imaging system based on the combination of ultrawideband transmission, multiple-input-multiple-output (MIMO) array, and synthetic aperture radar (SAR) is suggested and studied, showing a strong potential of the MIMO-SAR-based UWB system for security applications.

TL;DR: A 3-D near-field imaging algorithm that is formulated for 2-D wideband multiple-input-multiple-output (MIMO) imaging array topology that is able to completely compensate the curvature of the wavefront in the near- field through a specifically defined interpolation process and provides extremely high computational efficiency by the application of the fast Fourier transform.

TL;DR: UWB radar for detection and positioning of human beings in complex environment has been developed and manufactured and novel principle of human being detection is considered and verified experimentally.

TL;DR: A novel detection algorithm which is designed for detection of periodic motion caused by respiratory motion of the victim for low SNCR conditions is proposed, showing improved detection capabilities in low S NCR over an existing algorithm proposed by Zaikov et al.

TL;DR: In this article, a loading technique for improving pulse radiation from bow-tie antennas is introduced, which makes use of a combination of a constant resistive loading along the antenna and a capacitive loading with linearly increasing reactance toward the antenna ends.
