This proposal aims at developing an advanced detection and ranging sensor system based on a collaborative scheme, integrating on the same module both radio and light-based sensing. The module will consist of: a silicon photonics solid-state light detection and ranging (LiDAR) chip, with integrated laser source and driver electronics; a CMOS radio detection and ranging (RADAR) chip connected to a single transmitting (Tx) and receiving (Rx) set of antennas; a processing unit (PU) to actively control the two sensors and process the generated data. The LiDAR and RADAR chip will be integrated on the same printed circuit board (PCB) avoiding any use of free space optics. The proposed architecture will allow an active cooperation of the two sensors through an advanced algorithm installed on the PU. CoRaLi-DAR advanced sensor system will exploit LiDAR’s high-resolution capabilities, and RADAR’s strong reliability in adverse weather conditions, to deliver an automotive compatible detection and ranging system. The use of fully integrated photonics and electronics will reduce packaging size, manufacturing cost and ultimately operational power. With CoRaLi-DAR we plan to create a low-cost, low power and reliable sensor system that can be used as a platform for the automotive market and beyond.
