Abstract

Analytical expressions for the errors generated in 1 bit/2-level digital correlators (IB/2L) are derived: threshold errors in comparators and timing (skew and jitter) errors in samplers. These expressions are used to specify the parameters of the comparators and samplers in high performance 1B/2L digital correlators that are required in Earth observation synthetic aperture radiometry.
