Abstract :
A digital signal processor, operating at baseband, is described for the scanning of a Mills´ cross array antenna. The processor uses time modulation to scan the pencil beam produced by the array. The principles of time modulation scanning are reviewed. Experimental results are included to demonstrate the practical feasibility of the digital baseband processor for scanning the array along prescribed look directions inside the region of interest.
