The synthetic aperture radar (SAR) technique relies on knowledge of the relative motion
between the sensor and the target. If the flight path of the sensor is not accurately known or …

Two new motion compensation methods for airborne SAR are presented. Both methods are
based on the evaluation of acceleration data measured by an Attitude and Heading …

Abstract The Institute for Radio Frequency Technology of the German Aerospace Research
Establishment (DLR) in Oberpfaffenhofen operates an experimental synthetic aperture …

The performance of the reflectivity displacement method is reported. The reflectivity
displacement method extracts all the necessary motions of the aircraft from the radar …

Reported herein is the estimation of the residual error of the reflectivity displacement method
(RDM) and the dependence of RDM on terrain characteristics. The RDM is a method to be …

Conventional motion compensation schemes correct for unwanted SAR platform motions
using information from an inertial measurement unit (IMU). Autofocus techniques, which …

Ground imaging from an airborne synthetic aperture radar (SAR) and conversely aircraft
imaging from a ground based radar (ISAR) require the knowledge of the motion of the …

This paper addresses the problem of the compensation of the motion errors in an airborne
synthetic aperture radar (SAR). The motion errors are caused by the sensor's unintended …

The airborne use of synthetic aperture radars suffers from difficulties due to the
nonlinearities and the lack of accuracy in the measuring of the carrier trajectory. An …

Synthetic-aperture radar (SAR) has become an important tool for remote sensing of the
environment. However, until recently SAR systems, particularly airborne ones, have been …
