A general analysis of the impact of digitization in microwave correlation radiometers

Sensors (Basel). 2011;11(6):6066-87. doi: 10.3390/s110606066. Epub 2011 Jun 3.

Abstract

This study provides a general framework to analyze the effects on correlation radiometers of a generic quantization scheme and sampling process. It reviews, unifies and expands several previous works that focused on these effects separately. In addition, it provides a general theoretical background that allows analyzing any digitization scheme including any number of quantization levels, irregular quantization steps, gain compression, clipping, jitter and skew effects of the sampling period.

Keywords: correlation; digital; microwave; quantization; radiometers; sampling.
