QUALITY

Quality is part of the PERSEO Aresys python project, and it's aimed at providing fundamental functionalities for analyzing SAR data and quantitatively and qualitatively assess their quality and calibration features.

Quality
Example of quality graphical output obtained from Point Target Analysis.

The following analyses have been implemented:

Point Target Analysis : Impulse Response Function (IRF), Radar Cross Section (RCS) and Localization Errors

Radiometric Analysis : Noise Equivalent Sigma-Zero (NESZ), Average Elevation Profiles, Scalloping Profiles and custom radiometric profiles

Interferometric Analysis : interferometric coherence analysis and graphical representation

Spectral Analysis : absolute and phase spectral analysis for Point Targets and Distributed Targets

Elevation Notch Analysis : antenna pointing estimation from dedicated elevation notch products

Target Ambiguity Ratio (PTAR/DTAR) : ambiguity ratio analysis both for Point Targets and Distributed Targets

Equivalent Number of Looks (ENL) : equivalent number of looks analysis
