Non Ideal Motion in Airborne Sar: Analysis and Compensation
نویسنده
چکیده
Motion compensation is an important part of SAR processing for high resolution air borne imaging sensors. The non ideal motion of the platform carrying radar, results in degraded image quality. This paper concerns the analysis and compensation of trajectory deviations in airborne Synthetic Aperture Radar (SAR) systems. Analysis of the received data spectrum is carried out with respect to the system geometry in the presence of linear, Quadratic sinusoidal and general aircraft displacements and presents an efficient new motion compensation algorithm. This method is verified with simulated SAR data.

Improved SAR Motion Compensation without Interpolation
Motion compensation is an important part of SAR processing for high resolution airborne sensors, such as those flown on UAS’s. The non-ideal motion of the platform results in degraded image quality, but for known motion, corrections can be made. Traditional motion compensation requires a computationally costly interpolation step to correct translational motion greater than a single range bin. T...
متن کاملMotion Compensation in Bistatic Airborne
Common efficient SAR processing algorithms, e.g. Chirp Scaling (CS) and Omega-K are based on nominal operational conditions, that is, rectilinear flight trajectory and constant airborne attitude and forward velocity. Unfortunately, due to atmospheric turbulences and manoeuvring errors, these conditions are often violated in real SAR systems. Airborne sensors, in contrary to spaceborne sensors, ...
متن کاملExtended wavenumber-domain synthetic aperture radar focusing with integrated motion compensation
Modern synthetic aperture radar (SAR) systems are continually developing in the direction of higher spatial resolution. This requires the usage of high range bandwidths combined with long azimuth integration intervals. High-quality SAR processing methods, which are able to deal with such sensor parameters, are necessary for focusing the raw data of such sensors. Wavenumber-domain (v–k) processi...
متن کاملOptions for High-Precision Motion Compensation for Airborne Differential SAR Interferometry
In recent years, differential interferometry using space-borne SAR sensors has become an established technique for detecting and monitoring centimetre-scale deformations of the earth’s surface, as well as glacier flows and land slides. Although often very efficient, the use of space-borne SAR data has several drawbacks, namely phase artifacts caused by atmospheric effects and very low coherence...
متن کاملApplications of Time-Domain Back-Projection SAR Processing in the Airborne Case
The Back-Projection Algorithm is a SAR processing approach that uses time-domain convolution of the SAR data in order to perform SAR focusing. Some benefits of this approach are exact inversion, ideal motion compensation including topography information and handling of general aperture geometries. The implementation of the Back-Projection Algorithm was done focusing on the parallelization aspec...
