79 GHz UWB automotive short range radar – Spectrum allocation and technology trends

Abstract

Abstract. Automotive UWB (Ultra-Wideband) short range radar (SSR) is on the market as a key technology for novel comfort and safety systems. SiGe based 79 GHz UWB SRR will be a definite candidate for the long term substitution of the 24 GHz UWB SRR. This paper will give an overview of the finished BMBF joint project KOKON and the recently started successing project RoCC, which concentrate on the development of this technology and sensor demonstrators. In both projects, the responsibilities of Daimler AG deal with application based sensor specification, test and evaluation of realized sensor demonstrators. Recent UWB SRR frequency regulation approaches and activitites will be introduced. Furthermore, some first results of Daimler activities within RoCC will be presented, dealing with the packaging and operation of these sensors within the complex car environment.

Survey on Ranging Sensors and Cooperative Techniques for Relative Positioning of Vehicles

“…Therefore, the European Commission has made available the 79 band for long-term operation of radar sensors seeking worldwide harmonization. This band has the advantage that a common technology for short-range and long-range radars can be developed, along with the decreased dimension and weight and increased Doppler sensitivity [ 20 ]. The usage of the 24 UWB band has been prolonged until January 2018 [ 21 ].…”

Recent trends and advances in UWB positioning

“…Their current applications focus on logistics and supply chains in various industrial sectors. It is also worth noting the use of UWB in 1-D ranging in autonomous cruise control and driver assistance and safety systems available in the Mercedes-S Class and operates at both 77 GHz and 24 GHz [9]. As mentioned in [10], the integration of UWB RTLS with other technologies is the current trend driving the technology behind future RTLS.…”

Design of High Gain Novel Dielectric Resonator Antenna Array for 24 GHz Short Range Radar Systems

“…Automotive anti-collision radar systems have experienced remarkable development over the past ten years [1][2][3][4][5] thanks to the extensive and fast improvement in antenna R&D domain [6][7][8].…”

“…The SRR category is covering the most of automotive radar standardized frequency bands (24 GHz, 26 GHz and 79 GHz) in Narrow Band (NB) and UWB. The 24 GHz band has attracted many radar systems applications, summarized in figure 1 (a, b), like ACC support with Stop & Go functionality, collision warning, collision mitigation, blind spot monitoring, parking aid (forward and reverse), Lane change assistant and rear crash collision warning [2,9].
