In this paper, a K-band ground-based hyperspectral microwave radiometer for atmospheric
sounding is proposed, which improves the profile error and vertical resolution of moisture …

A passive millimeter-wave imager BHU-2D-U is introduced for detecting concealed
weapons on human body. It is a subsequent model of BHU-2D. The improvements of BHU …

This study presents an equivalent circuit and a design of an H-plane waveguide bandpass
filter (BPF) with chamfer. Traditionally, only thin inductive diaphragm with no chamfers …

The two-dimensional synthetic aperture interferometric radiometer (SAIR) technique is being
extensively employed in passive imaging systems. Compared to the other techniques, SAIR …

A highly integrated Ka band front-end receiver is presented. The proposed front-end
receiver is developed for a Ka band passive imaging system. The design adopts single …

In this paper, a nontrivial local oscillator uncorrelated phase noise analysis is proposed for
frequency synthesizer of a passive millimeter-wave Synthetic Aperture Interferometric …

As millimeter wave (MMW) electronic technologies have matured, the MMW imaging using
for human security inspection is emerging as an effective approach to imaging through …

In this paper we introduce the idea of integrating high security level services to support law
enforcement with high-tech crime investigation. We take advantage of a process-oriented …

A nontrivial phase noise analysis method is proposed for frequency synthesizer of a passive
millimeter‐wave synthetic aperture interferometric radiometer (SAIR) imager for concealed …

Microstrip filters are widely used in millimeter wave (MMW) circuit. This paper briefly
describes the design procedure of micro strip band stop filter. A compact band stop is …
