An Integrated mmW Radar Transceiver Enabling Fast Multi-Chirp Coherent IF Stitching
2024 IEEE Radar Conference (RadarConf24)(2024)
Abstract
The FMCW radars in mmW bands represent the major part of short-range solutions. The wideband sensing and spectrum sharing have an increased interest in the context of growing indoor and outdoor applications of short-range radars. In this paper, we suggest the use of an original radar architecture that addresses the coherent wideband sensing and spectrum sharing using a FMCW fast chirping radar transceivers. Theoretical system design approach and measurements based on the original architecture implementation expose the performance of IF frequency stitching technique in the context of short-range radar applications.
