This standard establishes performance metrics to assess the quality of image outputs from different airborne and space-based synthetic aperture radar (SAR) systems created using various algorithms. The system components that determine image quality include the raw collected data and the back-end processing algorithms. This standard provides: • A list of quantitative metrics that can be used to assess the quality of airborne and space-based SAR images. These metrics include peak signal-to-noise-ratio, integrated sidelobe level, speckle level, signal-to-clutter ratio, ambiguity signal ratio (ASR), noise equivalent sigma zero (NESZ), and feature contrast, • An analysis of the impact of different SAR geometries and imaging modalities on image quality, • An analysis of the impact of different focusing and autofocusing methods, computational metrics, different waveform modulations, platform position uncertainty, and quantization errors on image quality, • Uncertainties and confidence intervals for measured quantities that can be used to assess the quality of calibration routines.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
