How digital correlation affects the fringe washing function in L-band aperture synthesis radiometry

Abstract

The phase coherence limitations of L-band digital correlation radiometry are investigated for receiver architectures that use low A/D converter resolution (1–3 bits). Statistical models and measurements of a 1.4 GHz digital radiometer system show that coarse quantization can cause excess fringe washing losses which degrade the spatial resolution… (More)
