MICROWAVE DISTANCE MEASURING EQUIPMENT

摘要

PURPOSE:To measure at high accuracy by shifting and setting an antenna section to a distance between an object and antenna having small noise. CONSTITUTION:A microwave circuit 2 in the antenna section 16 mixes sending waves and receiving waves and detects beat waves. The beat waves are inputted to a period counting circuit 8 through an amplifier circuit 7, and beat period is counted. The distance between the antenna and a measured face is calculated by a distance calculating circuit 9 basing on the result of counting. A drive commanding section 10 determines optimum position of the antenna from the result of calculation and feeds drive command of the antenna section 16. On receiving this drive command, a driving device 11 drives the antenna section 16. The distance signal outputted from a distance correcting circuit 13 is led to outside from an output circuit 14.
