The analytical relations for indices of statistical quality of period estimates for correlation and covariation estimating methods are obtained. The methods of estimating the almost- PCRP probabilistic characteristics (using the least square methods) are worked out. The structure of signals from underground communications, which are obtained using electromagnetic marker system MC-3, are investigated. Signals from electromagnetic disturbance of non-fault rail are investigated. On the basis of the methods of creating PCRP parametrical models the probabilistic model of this signal are built.
