Behaviour comparison of the cumulative phase difference and the correlative integral module in application to the problems of the reference estimation of parameters of radioholographic objects

The present paper concerns the comparison of methods using cumulative phase difference (CPD) and correlation integral absolute value (CIAV) as a proximity measure, taking as an example a problem of reference estimation of parameters of holographic microwave imaging (SRGV) systems´ objects under study. It demonstrates that both methods outperform a classical system resolution limit.
