The Adaptive MTI System with Minimized Magnitude and Phase Distortions of the Processed Chirp Echo Signal

The article exhibits some issues associated with the nonlinear phase-frequency characteristic of the notch whitening filter based on a two-channel adaptive system with cross-control of filter weights arising from the chirp signal processing and with the distortion of such a signal caused by this non...

Zusammenfassung:The article exhibits some issues associated with the nonlinear phase-frequency characteristic of the notch whitening filter based on a two-channel adaptive system with cross-control of filter weights arising from the chirp signal processing and with the distortion of such a signal caused by this nonlinearity. An adaptive MTI system is proposed, using which the distortion of the useful chirp signal contained in the input unclassified observation sample is minimized during adaptive notch processing with cross-control of weights.
