“…The automotive application in the 77 GHz band has been one of the main drivers for research in this field [2]. However, the short-range sensing applications in the licence-free ISM band between 57 and 66 GHz, such as vital signs monitoring [3] and gesture recognition [4], have recently been drawing a lot of attention as well [5].…”

This work presents the design of a 24 GHz DCO in an advanced 28-nm bulk CMOS technology for short-range Frequency-Modulated Continuous-Wave radar System-on-Chip for mobile and Internet-of-Things devices. The power minimization is therefore the primary focus. The oscillator consumes a record low power of 1.2 mW at a 0.65 V supply voltage. It achieves a very large frequency tuning range of 5.8 GHz (27%) and a 150 kHz resolution without significantly degrading the phase noise. The proposed design methodology results in a State-of-the-Art −193 dBc/Hz FoMT.

“…T HE use of radar sensors for indoor applications has been enabled recently thanks to the enormous progress in radar miniaturization [1], [2] and energy efficiency [3], making use of the Frequency Modulated Continuous Wave (FMCW) design principle [4]. Among those indoor sensing applications, the navigation of small Unmanned Aerial Vehicles (UAVs) or drones is extensively being investigated for applications Ali Safa, Ilja Ocket, Francky Catthoor and Georges G.E Gielen are with imec and the Department of Electrical Engineering, KU Leuven, 3001 Leuven, Belgium (e-mail: Ali.Safa@imec.be; Ilja.Ocket@imec.be; Francky.Catthoor@imec.be; Georges.Gielen@kuleuven.be).…”

As radar sensors are being miniaturized, there is a growing interest for using them in indoor sensing applications such as indoor drone obstacle avoidance. In those novel scenarios, radars must perform well in dense scenes with a large number of neighboring scatterers. Central to radar performance is the detection algorithm used to separate targets from the background noise and clutter. Traditionally, most radar systems use conventional CFAR detectors but their performance degrades in indoor scenarios with many reflectors. Inspired by the advances in non-linear target detection, we propose a novel high-performance, yet low-complexity target detector and we experimentally validate our algorithm on a dataset acquired using a radar mounted on a drone. We experimentally show that our proposed algorithm drastically outperforms OS-CFAR (standard detector used in automotive systems) for our specific task of indoor drone navigation with more than 19% higher probability of detection for a given probability of false alarm. We also benchmark our proposed detector against a number of recently proposed multi-target CFAR detectors and show an improvement of 16% in probability of detection compared to CHA-CFAR, with even larger improvements compared to both OR-CFAR and TS-LNCFAR in our particular indoor scenario. To the best of our knowledge, this work improves the state of the art for high-performance yet low-complexity radar detection in critical indoor sensing applications.
