Summary :

This paper describes a DBF (Digital Beamforming) technique as a spatial filtering in the radar systems. DBF for a beamformer and an adaptive processor are discussed. An architecture for the beamformer is proposed. The beamformer discussed consists of systolic arrays that can form beams arbitrarily. Antenna radiation patterns measured in an open site are shown. For the adaptive processor, Gram-Schmidt transformation method is attained by using systolic arrays. Proposed is a means to prevent target signals from being suppressed in cells of the systolic arrays and to achieve the convergent characteristics independent of the magnitude of undesired signal power. In order to demonstrate the performance of the proposed processor, a test model of the adaptive processor was developed and tested in multiple undesired signal environment. Test results are indicated.
