Abstract. Integral phase maximum likelihood and method of moments estimation procedures are analyzed in application to minimum-phase method. Their bias’ and variances’ dependence on signal-to-noise ratio, noiseless integral phase and sample size are analyzed. A qualitative study of behavior of estimates for different practical scenarios is performed. The obtained characteristics can be used to specify the required sample size for assuring fixed test-set step and for test-set construction in case of prespecified sample size. Guidelines for design process of the holographic system exploiting minimum-phase method are proposed.
