Abstract :
Design and characteristics of a prototype distance sensor are presented in this paper. The radar front-end operates at 35 GHz and applies six-port technology and direct frequency measurement. The sensor makes use of both frequency-modulated continuous wave and interferometer principles and is capable of measuring distance with a very high accuracy of ±0.1 mm
