As a cutting-edge research direction in the field of radar imaging, video SAR has the
capability of high-resolution and persistent imaging at any time and under any weather …

A terahertz (THz) airborne synthetic aperture radar (SAR) with a carrier frequency of up to
220 GHz is developed. However, due to the short wavelength of THz, the motion …

In a wide-angle synthetic aperture radar (SAR), as the isotropic scattering assumption
becomes invalid, scattering characteristics of targets tend to be aspect-dependent. In this …

For conventional polar format algorithm (PFA), because of the image distortion and defocus
caused by the plane-wave assumption, the effective imaging scene is bounded to a small …

The automotive synthetic aperture radar (SAR) can obtain two-dimensional (2-D) high-
resolution images and has good robustness compared with the other sensors. Generally, the …

In this paper, a terahertz (THz) radar security imaging method for multi-target screening is
proposed. This imaging system is constituted of several transceivers to get multi-angle echo …

This paper deals with the problem of fast focusing the spotlight synthetic aperture radar
(SAR) data in high-resolution and high-squint mode, which has shown its potential capacity …

Video synthetic aperture radar (ViSAR) is a novel imaging mode where the radar system
forms a sequence of SAR images while the radar platform is flying. To achieve a high frame …

The polar format algorithm (PFA) is a frequency-domain algorithm with high computational
efficiency especially for the high resolution imaging applications in wide-angle staring …

By means of alteration of the transmitted linear frequency modulation (LFM) signal waveform
parameters, such as pulse width or chirp rate, initial phase, pulse repetition interval (PRI) …
