We present an adaptive algorithm for real-time calculation of correlation functions with a sliding window for stationarity analysis. This window moves with a one-sample discreteness. The stationarity analysis of a casual process consists in the comparison of means and variances of the process on the current analysis interval and the current confidential interval. Variance errors for the algorithms with a crossbar window and a sliding window are compared. Block diagram of an adaptive on board correlator is presented.
