S80 77 GHz 4D Digital Imaging Radar-on-Chip
Overview
The S80 is a fully integrated 77 GHz, 4D Imaging Radar-on-Chip (RoC) with Digital Code Modulation (DCM) certified for use in key automotive safety applications, such as automatic emergency braking, lane keep assist, adaptive cruise control, and blindspot detection, as well as automated driving functions, including autonomous vehicles.
The RoC uses a PMCW (phase modulated continuous wave), MIMO (multiple-input multiple-output) radar architecture capable of processing up to 192 virtual channels. It supports 12 transmit antenna channels (Tx) and 16 receive antenna channels (Rx). The S80 is fully software-defined, has built-in processors to run algorithms on-chip and can also enable optimization with deep learning neural networks and AI (artificial intelligence) found in the most advanced automated perception systems. The device’s DCM minimizes mutual interference from neighboring radars and provides high contrast resolution (HCR) delivering maximum discrimination, as well as high-confidence detection of independent targets, including vulnerable road users (VRUs), such as pedestrians and cyclists, in long- (LRR), mid- (MRR), and short-range radar (SRR) applications.
