Suboptimal Simulation and Suppression of Clutter Signals

Two digital filters are presented, which are suited for generating (Correlation) or suppressing (decorrelation) by approximation time-discrete signals with preset autocorrelation function from white noise. The advantage of these suboptimal filters is that the determination of their coefficients is very simple. For this reason the filters are weil suited for generating or suppresing signals with rapidly varying statistical parameters. One application possibility is the simulation and the adaptive suppression of clutter signals in surveillance radar systems.
