76-81 GHz CMOS mm-wave signal generator by Fujitsu for Automotive Radar

Radar and the Lidar are the two key technologies used in self driving or autonomous cars to detect objects. The drawback with Lidar is, in rainy season or during foggy environment Lidar fails to detect objects whereas radar is useful even in those conditions. Fujitsu announced a component for radar which makes the radar further accurate. The CMOS millimeter-wave signal generator from Fujitsu for automotive radars can modulate frequencies in the band width range of 76-81 GHz. The new signal generator device supports detection of objects at relative speed of 200km/hr, that means if two cars facing each other at a speed of 100km then also these CMOS signal generators can successfully detect objects. These CMOS sensors can detect pedestrians, bicycles or such moving objects on the road accurately. By this Millimeter Wave signal generator and also by using another device called four-channel CMOS transmitter circuit from Fujitsu, it is be possible to measure and control millimeter - Wave beams with a phase precision within 1 degree. The users can scan their surrounding with a high level of precision at high speed, according to Fujitsu. Fujitsu presented this technology at an event called European Microwave Week 2016 (EUMW 2016), which was held on October 3-7, in London. The idea behind this chip is to expand the use of radar from 77-GHz band to broader band of 79 GHz. These ra...
