Researchers at Princeton University, Germany's Ulm University and University of Kassel, Mercedes-Benz, and Canadian software firm Algolux have developed an automated radar system that will enable cars to look around corners and spot oncoming hazards. The system employs Doppler radar to bounce radio waves off surfaces at an angle to detect occluded objects and determine if they are moving or stationary. Radar's spatial resolution is relatively low, but the researchers think they could design algorithms to read the data to allow the sensors to operate. The team used artificial intelligence techniques to refine processing and interpret the images, focusing on background noise rather than usable information to distinguish objects. Princeton’s Felix Heide said, “In terms of integration and bringing it to market, it requires a lot of engineering. But the technology is there, so there is the potential for seeing this very soon in vehicles.”
