We present a reconfigurable, dynamic beam steering holographic metasurface aperture to
synthesize a microwave camera at K-band frequencies. The aperture consists of a 1D …

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 millimeter-wave (mmW) classifier system applied to images synthesized from a coded-
aperture based computational imaging (CI) radar is presented. A developed physical model …

Electromagnetic (EM) waves at millimeter-wave (mmW) frequencies have found applications
in a variety of imaging systems, from security screening to defense and automotive radars …

There is an increasing demand in real-time imagery applications such as rapid response to
disaster rescue and security screening to name a few. The throughput of a radar imaging …

Computational imaging systems leverage generalized measurements to produce high-
fidelity images, enabling novel and often lower cost hardware platforms at the expense of …

The resolution of terahertz images based on the near-field synthetic aperture radar (NSAR)
imaging mode is low due to the narrow antenna beamwidth and the electromagnetic wave …

The goal of this work is to develop a technology that can reduce recognition computational
complexity with the rise of recognition quality. We use an approach based on …

In this paper, a frequency-wavenumber decoupling algorithm with high-efficiency and high-
precise for three-dimensional (3-D) multiple-input-multiple-output synthetic aperture radar …
