نویسندگان
چکیده
This article explores the SAR back-projection algorithm for stripmap image formation and its characteristics. The article provides a derivation of generalized time-domain back-projection from first principles. It shows that back-projection may be considered an ideal matched filter for SAR. The article presents an analysis of the sensitivity of back-projection to its geometric parameters as well as several performance considerations: azimuth beam width, residual phase error, digital elevation map accuracy, and antenna position estimation accuracy.

Model-Based Autofoceus for Stripmap SAR Images Formed via Convolution Back-Projection
Many autofocus algorithms exist for correcting uncompensated residual phase errors in SAR images. These algorithms depend on the SAR modality (i.e. spotlight, stripmap, etc.). In this paper, we develop a model-based phase error estimation method and apply it to correct the phase error for stripmap SAR images formed via convolution backprojection (CBP). Our phase estimation method uses classical...
متن کاملGPU Processing for UAS-Based LFM-CW Stripmap SAR
Unmanned air systems (UAS) provide an excellent platform for synthetic aperture radar (SAR), enabling surveillance and research over areas too difficult, dangerous, or costly to reach using manned aircraft. However, the nimble nature of the small UAS makes them more susceptible to external forces, thus requiring significant motion compensation in order for SAR images to focus properly. SAR back...
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...
متن کاملProcessing SAR data of rugged terrain by time-domain back-projection
Processing of SAR images of rugged terrain deserves special care because the topography affects the focused image in a number of ways. In order to obtain geometrically and radiometrically corrected SAR images of mountainous areas additional knowledge about the topography and the sensor’s trajectory and attitude has to be included in the processing or post-processing steps. Various well-known fo...
متن کاملA Tool for Planning of High Resolution / Wide Coverage Imaging Radars
The hybrid stripmap/spotlight operating mode for Synthetic Aperture Radar (SAR) system is able to generate microwave images with an azimuth resolution better than that achieved in the stripmap configuration, and a ground coverage better than the one of the spotlight configuration, thanks to the radar antenna beam steering about a point farther away from the radar than the area being illuminated...
