Reports Outline Microwave and Wireless Technologies Study Results from University Erlangen-Nurnberg (Lens-based 77 GHZ MIMO radar for angular estimation in multitarget environments)

By a News Reporter-Staff News Editor at Journal of Technology -- Current study results on Microwave and Wireless Technologies have been published. According to news reporting from Erlangen, Germany, by VerticalNews journalists, research stated, "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 77GHz time domain multiplex (TDM) MIMO radar is presented."

The news correspondents obtained a quote from the research from University Erlangen-Nurnberg, "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."

According to the news reporters, the research concluded: "Due to the usage of these techniques the sensor performance in accuracy, ambiguity suppression, and angular resolution can be significantly increased."
