In this paper the evolution of silicon based automotive radar for the 76-81 GHz range is described. Starting with SiGe bare-die chips in 2009, today packaged MMICs are available for low-cost radar applications. Future SiGe BiCMOS technology will enable highly integrated single chip radars with superior performance at lower power consumption. This will pave the way for automotive radar safety for everyone and will be an important step towards autonomous driving.

The demanding tasks for automotive radar systems in multitarget scenarios require an increased target separation performance and new sensor concepts. In this contribution, a highly integrated 77 GHz time domain multiplex (TDM) MIMO radar is presented. The sensor is feasible for advanced direction of arrival (DOA) estimation in azimuth and elevation. For efficient and high-quality measurements a fractional-n phased locked loop (PLL) with integrated waveform generator, enabling chirp and frequency modulated continous waveform (FMCW) modulations, is implemented. Spatial beamforming is done with series feed array patch antennas in combination with a dielectric cylindrical lens. For the improvement of the direction of arrival (DOA) estimation performance a new lens-based MIMO radar approach is introduced. Therefore the classical MIMO approach is combined with the advantages of an optical beamforming concept. Due to the usage of these techniques the sensor performance in accuracy, ambiguity suppression, and angular resolution can be significantly increased.

“…Industrial research strongly focused on bringing the costs of the technology down in recent years, see e.g. rfpackages in [24] and SiGe-technology for automotive MMICs [25,26]. Concerning the MMIC CMOS and SiGe (BiCMOS) are candidates for future automotive radars, even in the frequency range at 158 GHz, see e.g.…”

“…On the other hand there are some hints that there might be limits on CMOS for automotive MMIC as shown in [31]. Concerning packaging, many different approaches are under investigation or are already in use [25,26], again even up to 170 GHz, see [32].…”
