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

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 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

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

In this paper, integration of an UWB array-based time-domain radar sensor in a vehicle-mounted multi-sensor system for landmine detection is described. Dedicated real-time signal processing algorithms are developed to compute the radar sensor confidence map which is used for sens

In this paper two novel MIMO UWB antenna arrays have been proposed for through dress imaging radar application. The advantage os using MIMO array is that the number of elements can be reduced and the element spacing can be sparser than that of SIMO array, while the performance wi
