Paper Abstract

In system performance analysis, most often Signal to Noise Ratio (SNR) and system resolution (via MTF) are analyzed separately. In this paper we advocate the use of a joint measure, namely, the Noise Equivalent Reflectance Difference (NERD) as a function of the Spatial Resolution (SR). We demonstrate that the NERD vs. SR captures most of the essential properties of the system's performances and is therefore a useful tool in system evaluation. We demonstrate how various tradeoffs affect the NERD vs. SR curve in some not so trivial way.
