The principles of auto compensation and construction of Doppler auto-compensators of multifrequency clutter with inter-channel averaging of estimates are proposed. The aim of the paper is to analyze the accuracy of auto-compensation depending on frequency channel number and training sample size determined by the number of averaged samples in each frequency channel and correlation properties of the clutter in frequency channels. It is shown that inter-channel averaging of estimates significantly improves the accuracy of estimation and compensation of Doppler multifrequency clutter phase shifts. Correlation matrices are obtained at the outputs of rejection filters in frequency channels, which open up the possibilities of subsequent analysis of the efficiency of processing systems for multifrequency signals, taking into account the substantial increase in the accuracy of estimation and compensation of Doppler clutter phase shifts due to interchannel averaging of the estimates introduced in auto-compensator.

Key words: auto-compensation, Doppler phase, multifrequency signal, multifrequency clutter, training sample, rejection filter, accuracy of auto-compensation, correlation matrices.
