Insufficient accuracy of trajectory measurements is a pressing problem for modern high-
resolution airborne SAR systems. In the paper, a novel method for the estimation of residual …

Due to the presence of atmospheric turbulences, airborne SAR raw data may be affected by
deviations of the platform from an ideal straight line. Additionally, being rather expensive, the …

The main goal of this work is to obtain high-resolution SAR images without precise
information of the flight parameters. The paper presents advanced Autofocus Map Drift …

High-resolution imaging with an airborne synthetic aperture radar (SAR) calls for precise
trajectory measurements that can hardly be achieved with common navigation systems. In …

When processing airborne SAR data, motion compensation is an unavoidable step.
Accurate motion compensation requires the knowledge of the exact position of the platform …

Airborne synthetic aperture radar (SAR) systems are very sensible to deviations of the
aircraft to the reference flight path. The trajectory errors can be divided into along-azimuth …

The quality of high-resolution SAR imaging is strictly related with the precision of the
platform trajectory measurements. This is one of the crucial points in the case of image …

Due to the lack of accuracy in the navigation system, deviations in the order of centimeters
between the real trajectory and the measured one, called residual motion errors (RMEs) …

Formation of high-resolution SAR images from light-weight platforms is a challenging task
primarily due to high instability of such platforms. Additional difficulties are related with the …

The paper presents concept of the coherent autofocus map-drift technique. The main goal of
this work is to obtain high accuracy and sensitivity for autofocus technique in strip-mode …
