In this paper, brief deals with a new initialization technique for digital IIR filters. The technique is suitable for IIR filters processing a finite number of samples in phased array radars. The initialization processor is complex one and utilized the first received sample to force the filter to reach its steadystate value at a single frequency irrespective of the number of processed samples. This is process is reached by initially loading the internal memories of the filter with their steady-state values. If the filter has a zero steady-state response at that particular frequency then this will ensure that the transient frequency responses of the filter will also have a zero response at that frequency. Different processors are derived for filters with real and complex coefficients.
