A 79 GHz SiGe short-range radar sensor for automotive applications

Abstract

The field of short- and mid-range radar sensors for automotive comfort and safety systems is a fast-growing market. The frequency regulation provides a new 76–81 GHz frequency band, which will be mandatory in the EU for ultra-wideband sensors from 2018. In the “radar-on-chip for cars” (RoCC) project funded by the German Ministry of Research (BMBF), a new technology was developed based on SiGe components with the objective to make the sensors affordable for all car platforms. This paper reports on the contribution of Continental A.D.C. GmbH to the joint “RoCC” project. The aim of the project was to exploit the cost-reduction potential of the SiGe technology by a further integration of the individual components and to show that the reliability and the functionality of the new sensors can meet the current requirements of the market. For this purpose, we evaluated the new eWLB package technology of Infineon. The Institute of Microwave Techniques of the University of Ulm supported us in designing a substrate integrated slotted waveguide antenna array. Demonstration sensors for short- and mid-range applications were built up and tested in the laboratory. To show the ability of the sensors to deal with real scenarios on the road, they were integrated into an experimental vehicle.

Multiple-target tracking and track management for an FMCW radar network

“…The numerical experiments are performed to evaluate the performance of the proposed track management system in maintaining vehicle tracks. The experiments, however, are not intended to address automotive applications, where radar signals are coherently processed [3,4].…”

“…Millimeter-wave frequency-modulated continuous-wave (FMCW) radars have a great popularity in diverse applications owing to their simplicity, low cost, and robustness in rain, humidity, fog, and dusty conditions [1,2], and they are often deployed as medium-and long-range radars for the purpose of driver and transportation safety [3,4]. The radars are also utilized in ground and maritime surveillance systems for tracking targets [1,5,6].…”

A 79-GHz LTCC patch array antenna using a low-loss ceramic tape

“…The measured gain of the antenna at the WR12 flange is 15.4 dBi. As comparison, the antenna parameters realized on LTCC and organic substrate [15] are listed in Table II.…”

A Ferrite LTCC-Based Monolithic SIW Phased Antenna Array

“…While the slot offset from the SIW center (referred to using the symbol x) mainly dictates the slot conductance at resonance G 0 . To extract the slot admittance, the procedure in [25] has been utilized. A single slot is simulated with the wave guide being terminated by a short circuit at a distance of 3λ g /4 form the slot center and with the port plane being at λ g /2 before the slot center.…”
