Signal processing for target detection in experimental phased-array radar ELRA

The concept and some experimental results of the phased-array system ELRA are presented, with emphasis on signal processing for target search. Multiple beams together with a variable number of pulses in each beam position are used for sequential detection and also for search in clutter by applying a recursive filter against stationary target echoes. New considerations concerning the practical application of sequential detection for multiple range elements, even in cluttered areas, are discussed.
