For analysis of relation between two PCRP-processes in frequency domain the formulae for coherence functions are grounded, these formulae are useful for detection and separation of different defects. On the base of analysis of simulated rolling bearing vibrations uses methods of vectorial PCRP the efficiency of using as linear as quadratic invariants of correlation tensor-function for detection of bearing state and defects detection is shown.
