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.
Key words: parameter estimation, radioholographic system,
reference set method, integral phase difference.
