In this paper, we provide a review of the different approaches used to detect activities inside
a building using through-the-wall radar. We classify two main types of radar that are used in …

In this paper, we discuss using field-programmable gate arrays (FPGAs) to process either
time-or frequency-domain signals in human sensing radar applications. One example will be …

The resolution of a frequency diverse compressive metamaterial aperture imager is
investigated. The aperture consists of a parallel plate waveguide, in which an array of …

Generalized Lorenz‐Mie theories form a set of analytical approaches dealing with the
interaction between electromagnetic arbitrary shaped beams and a class of particles …

We demonstrate a frequency diverse, multistatic microwave imaging system based on a set
of transmit and receive, radiating, planar cavity apertures. The cavities consist of double …

We present the design and simulation of a frequency-diverse aperture for imaging of human-
size targets at microwave wavelengths. Predominantly relying on a frequency sweep to …

A fast low-cost through-the-wall radar imaging (TWRI) system, based on a vector network
analyzer (VNA), a couple of switches and an array of Vivaldi antennas, has been designed …

Dynamic metasurface antennas (DMAs) have recently been introduced as a computational
imaging (CI) platform that offers significant advantages over conventional imaging systems …

A frequency‐diverse computational imaging system synthesised using three‐dimensional
(3D) printed frequency‐diverse metasurface antennas is demonstrated. The 3D fabrication …

We propose a polarimetric microwave imaging technique that exploits recent advances in
computational imaging. We utilize a frequency-diverse cavity-backed metasurface, allowing …
