Abstract :
We report a first W-band 1/spl times/4 direct detection radiometric imaging array based on MMIC technology. The imaging array was integrated with a W-band radiometric imaging system. Field image taken by the 1/spl times/4 imaging array in stepping push-broom mode shows excellent results. Successful demonstration of the 1/spl times/4 W-band radiometric imaging array indicates not only the maturity of MMW MMIC technology but also the feasibility of larger linear or two-dimensional radiometric imaging array based on the simple MMIC direct-detection approach.<>
