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.

Key words: microwave imaging, parameter estimation, threshold effect, Cramer-Rao bound, Chapman-Robbins bound.
