In this paper, an extended nonlinear chirp scaling (ENLCS) algorithm for focusing synthetic
aperture radar data acquired at high resolution and highly squint angle is proposed. The …

Highly squint synthetic aperture radar (SAR) data focusing is a more challenging and difficult
task than the side-looking SAR due to the strong 2-D coupling of echo signal induced by the …

In this letter, several important aspects are addressed for highly squinted synthetic aperture
radar data with subaperture (SA) processing. First, the influences of the reference linear …

Since synthetic aperture technology was employed in radar signal processing, the
information capability of radar has greatly been enhanced. A lot of imaging algorithms have …

The results of the linear range cell migration (RCM) correction and inherent range-
dependent squint angle in the case of high-resolution highly squinted synthetic aperture …

The signal processing of the medium-Earth-orbit synthetic aperture radar (SAR) is more
challenging than that of the current low-Earth-orbit SAR because the imaging geometry is …

Accurate focusing of highly squinted azimuth-variant bistatic synthetic aperture radar data is
a difficult issue due to the relatively large range migration, sensibility of the higher order …

Bistatic synthetic aperture radar data are more challenging to process than the common
monostatic counterparts because the flight geometry is more complicated and the data are …

Since synthetic aperture technology was employed in radar signal processing, a lot of
imaging algorithms have been developed for highly squinted synthetic aperture radar (SAR) …

To process squinted sliding-spotlight synthetic aperture radar data, the azimuth
preprocessing step based on the linear range walk correction (LRWC) and derotation …
