An ultra-wideband radar imaging system using a two-dimensional multiple-input multiple-output (MIMO) transducer array

A radar transducer array (12) for an ultra-wideband imaging radar system (10) operating at a reference wavelength ?c comprises transmission antenna elements (14) or reception antenna elements and reception antenna elements (16), which are located at specific locations of the array plane in such a way that high image quality is achieved with a...

Comparison of 10–18 GHz SAR and MIMO-based short-range imaging radars

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 mechanical scanner. The second one makes use of a multiple input...
