Radar Generalized Image Quality Equation Applied to Capella Open Dataset

The National Imagery Interpretability Rating Scale (NIIRS) is a numeric scale of semantic criteria used to quantify the visual interpretability of imagery products. The Radar National Imagery Interpretability Rating Scale (RNIIRS) is the version used to rate imaging radar products, specifically Synthetic Aperture Radar (SAR). RNIIRS is specified by imagery users to describe the visual interpretability requirements for the task at hand and is a subjective, scene dependent estimate. A predictive equation called an Image Quality Equation (IQE) is employed based on sensor collection parameters such as Impulse Response (IPR) and Signal to Noise Ratio (SNR) to predict the RNIIRS value of a scene. This paper proposes a quantitative and objective measure to predict SAR image quality to replace these subjective measures.
