Radar on a chip reduces sensor costs

European research project SUCCESS has developed a low-cost radar system which could help reduce the costs for some of the autonomous car sensors. The tiny chip contains all required high frequency processing components and even includes the antenna! The radar operates in the 122GHz band and has a wavelength of 2.5mm. It can measure distances and velocity of moving objects within a range of up to 5 meters with high precision. The sensor was developed by a consortium of European companies including Bosch, Silicon Radar and the Karlsruhe Institute of Technology. At an estimated price of less than 2 U$ the chip has a wide field of potential applications and may be especially attractive for smaller autonomous devices where it could replace currently used ultrasound sensors.
