Intel and Mobileye develop LiDAR in a Chip
13 January, 2021
According to Prof. Amnon Shashua, President and CEO of Mobileye, the new sensor is based on Frequency-Modulated Continuous Wave (FMCW) technology and Doppler-style algorithms
Mobileye announced during CES 2021 this week that it has produced the first prototype of an Automotive LiDAR sensor based on Intel’s Silicon Photonics technology. The new sensor is planned to be installed in its Autonomouse Driving systems in 2025, when the market will be ready for a mass deployment of AVs. According to Prof. Amnon Shashua, President and CEO of Mobileye, the new sensor is based on Frequency-Modulated Continuous Wave (FMCW) technology and Doppler-style algorithms as opposed to the current Time of Flight sensors.
The FMCW sensor provides 4D velocity relative measurements for a distance of up to 300 meters. Its high resolution detection capability reaches 600 points per degree, created by 2 milliom laser pulses per second (2M PPS). The idea is that current approaches and available sensors are too expensive for consumer AVs. Mobileye needs Radars and LiDARs that are both better and cheaper. To reach L5 autonomy it propose three levels of redundancy in the forward-facing field of view (FoV), and for the rest of the FoV, 2 levels of redundancy.
In this scenario, the EV system consists of 360⁰ camera coverage, 360⁰ Radar cocoon and one forward-facing LiDAR sensor. In fact, Intel owns a unique Fab capable of putting active and passive optical elements on a chip together, including lasers and optical amplifiers, loaded onto a photonic integrated circuit, PIC.
The goals for the future radar chip are also very agressive: It will be a software-defined imaging radar eqipped with 2,304 virtual channels based on 48 by 48 transmitters and receivers. This radar will be able to detect motorcycles beyond 200m, old tire on the road, 140 meters away and low and small hazards on the road.
