A 6 mm monopulse AC direction guiding system

A 6 mm experimental prototype of direction guiding is presented in the paper. It uses two pairs of beams, /spl Sigma///spl Delta/ and A/B, for searching and guiding of target direction respectively, based on monopulse amplitude-comparison technique. The measured results show an accuracy of better than 2/spl deg/ RMS to be obtained over 6 mm frequency band by the help of a three antenna construction.
