This paper discusses the effect of motion measurement errors (MMEs) on measured bistatic
synthetic aperture radar (SAR) phase history data that has been motion compensated to the …

In recent papers the authors discussed the advantages of forming spotlight-mode SAR
imagery from phase history data via a technique that is rooted in the principles of phased …

Relatively small motion measurement errors manifest themselves principally as a phase
error in Synthetic Aperture Radar (SAR) complex data samples, and if large enough become …

Uncompensated phase errors lead to quality degradation of SAR images what is especially
critical for high-resolution systems. In the paper, a novel approach to the stripmap autofocus …

A challenge in SAR system development involves compensation for nonlinear motion errors
of the sensor platform. The uncompensated along-track motions can cause a severe loss of …

This paper presents an experimental Synthetic Aperture Radar (SAR) system that is under
development in the Universidad Politécnica de Madrid. The system uses Linear Frequency …

Synthetic aperture radar (SAR) imaging methods are designed to image stationary scenes.
Moving targets appear smeared and misplaced in reconstructed SAR images. This paper …

General Atomics Aeronautical Systems, Inc.(GA-ASI) is designing a real-time, video-SAR
(synthetic aperture radar) mode for a test bed radar system. Typically, the flight path for video …

The phase gradient autofocus (PGA) algorithm has been widely used in spotlight synthetic
aperture radar (SAR) to remove motion-induced blurs in the images. The PGA algorithm has …

Conventional motion compensation schemes correct for unwanted synthetic aperture radar
(SAR) platform motions using information from an inertial measurement unit (IMU) …
