Abstract :
Design and characteristics of a prototype distance sensor are presented. The radar front-end operates at 35 GHz and applies six-port technology and direct frequency measurement. The sensor makes use of both FS-CW and interferometer principles and is capable of measuring distance with 0.1 mm accuracy.
