Abstract:
A method for signal-to-noise ratio assigning the threshold effect in
signal parameter estimation is proposed. The approach relies on the divergence
between the Cramer-Rao and Chapman-Robbins lower bounds for variances of the
obtained estimates. The proposed methods’ validation is illustrated with an
example of cumulative phase estimation in phase template matching method for
microwave imaging applications.
