Linear array synthetic aperture radar (SAR) can achieve 3-D high-resolution imaging, which
provides a novel scattering diagnosis technique. However, high sidelobes and background …

Antennas and metasurfaces have enabled a number of far-field manipulation functions.
According to the addition theorem of multipoles, near fields have richer spatial spectra than …

Metamaterials are created by arranging small scatterers in a regular array throughout a
space to manipulate electromagnetic waves. However, current design methods view …

In this paper, a near-field (NF) 2-D-lateral scan system is conceptually described. The
analysis of the system is formally performed in a general manner from the modelization of …

The interrupted transmitting and receiving (ITR) has been utilized in radio frequency
simulation to conduct target measurement with pulse signal. Because the ITR results in a …

It is challenging to perform the near-field to far-field transformation with a high precision for
the multiple-scattering targets using the conventional monostatic radar cross section (RCS) …

This letter presents an improved back-projection (BP) technique for far-field radar cross
section (RCS) feature extraction from near-field measurement. The presented technique can …

Target detection based on time reversal (TR) effectively uses multipath effects to achieve the
space-time focusing effect and enhance radar detection performance by adaptively …
