In this paper a novel 61GHz radar sensor node for industrial positioning and distance measurement is presented. The sensor provides numerous functions enabling a broad range of signal processing technologies and is designed with regard to cost-efficient implementation only using commercial available components without limiting the area of possible applications. Beside the requirement analysis and...
This paper describes a new method for high accuracy determination of instantaneous frequency and linearity of frequency modulated continuous wave systems. The presented setup reduces the frequency measurement to a phase measurement based on Six-Port interferometer with a delay line. To extend the range of possible input frequencies and power levels, a calibration method and the appropriate correction...
Radar sensors play a key role in today's industrial automation. Being an alternative to frequency modulated continuous wave radar, Six-Port based radar sensors recently attracted the interest of the community as well as of the industry. This paper presents a 61 GHz Six-Port radar sensor for ultra-short range applications and a dedicated substrate integrate waveguide fed tapered slot antenna design...
