In this paper, we investigate the feasibility of utilizing the concept of effective aperture for designing sparse multiple-input multiple-output (MIMO) array oriented for ultrawideband (UWB) near-field imaging. The array design approach based on the effective aperture concept was

This paper presents an experimental investigation of two approaches to short-range radar imaging at microwaves by means of ultra-wideband (UWB) technology. The first approach represents a classical synthetic aperture radar (SAR) that employs a transmit¿receive antenna pair on mec

This paper investigates the performances of a wavefront-based shape reconstruction algorithm, known as Envelope, for ultra-wideband (UWB) near-field imaging. In contrast with conventional beamforming, surface estimation is based on identification of wavefronts within the received

In this paper, the design of a low profile circularly tapered antipodal Vivaldi antenna for array-based UWB near-field imaging is presented. The proposed circular termination at the end of radiating flare and optimization of the feeding transition result in extension of the opera
