In the past few years, great effort has been devoted to the fabrication of highly efficient,
broadband radome and stealth (R&S) structures for distinct control, guidance, surveillance …

This paper presents a microwave camera design operating in the 20–30 GHz frequency
range and capable of producing 3-D images at video frame rate (ie, real-time), using …

Accessing to glass fibre reinforcement plastic (GFRP) pipes in the on-line process is often
limited to one side. To detect an internal defect of coated GFRP pipe, common non …

The discrete fractional Fourier transform (DFRFT) plays an important role in processing time-
varying signals. Nevertheless, directly computing the DFRFT involves high complexity …

The effect of antenna gain pattern on synthetic aperture radar (SAR) imaging is analyzed in
this article. In prior investigations, only the effect of antenna half-power beamwidth (HPBW) …

Wideband synthetic aperture radar (SAR) technique is a robust imaging tool for microwave
and millimeter-wave imaging such as nondestructive evaluation applications. In this paper …

In near-range sparse multiple-input multiple-output (MIMO) array imaging, since grating
lobes spread wide and overlap with each other, the grating lobes and the zeros of the …

This paper reports the experimental studies for four image reconstruction methods from
sparse measurement using wideband microwave synthetic aperture radar systems. The four …

This article presents a multistatic or multiple-input–multiple-output (MIMO) antenna array
millimeter-wave imaging system operating in the Ka-band (26.5–40 GHz) frequency range …

A method to extract the complex permittivity from synthetic aperture radar (SAR) images of
multilayered structures is proposed. Specifically, a three-term one-port calibration method is …
