The paper derives a chirp scaling (CS) algorithm for arbitrary transmitter and receiver motion
(nonparallel tracks, unequal velocities and antenna squint) in a bistatic synthetic aperture …

The imaging in geosynchronous synthetic aperture radar (GEO SAR) is more difficult than
that of the conventional low earth orbit (LEO) SAR. This paper discusses the problems in …

This paper presents an efficient phase preserving processor for TOPS (Terrain Observation
by Progressive Scans) imaging mode. TOPS has been proposed as a new wide swath …

We present a new solution for the phase-preserving focusing of synthetic aperture radar
(SAR) raw data acquired through the Terrain Observation with Progressive Scan (TOPS) …

This paper presents the practical spaceborne synthetic aperture radar (SAR) data focusing
method based on the realistic end-to-end spaceborne SAR simulation. Our simulation …

Presents new range and azimuth scaling functions which can be introduced into the
processing of SAR and ScanSAR data for automatic geometric scaling in range and azimuth …

In the case of high range resolution and squint angle, current chirp scaling algorithm (CSA)
and nonlinear CSA (NCSA) have a finite ability to achieve high-quality images. The problem …

The azimuth multi-channel synthetic aperture radar (MC-SAR) systems can simultaneously
realize high-resolution and wide-swath (HRWS) earth observations. However, channel …

This paper presents a nonlinear chirp scaling in processing monostatic and bistatic SAR
data. When the effects of quadratic range migration are negligible, a time domain range cell …
