“Analog radar uses frequency modulation,” Reddy tells us. “Phase modulation in digital provides interference robustness.”
Every radar has a quintillion unique code embedded into the signal. That means every signal sent from the unit is unique. Not only is the radar looking for the return signal, but also if the inbound signal has the unique code.
In an intersection with various cars, for example, cars have to now try to figure out which radar is theirs and which radar is from the opposing vehicles. With digital radar, that confusion is eliminated by the unique identifier.
There aren’t any sacrifices going to digital, either. We’re told that this new radar technology has a range of greater than 300 meters. In comparison, our long-term Model 3 has a 200 meter radar unit, and most analog radar units work from 150 to 200 meters.
Additionally, the digital radar has a range of 150 meters for pedestrian detection. Digital radar’s resolution allows it to pick up things never before distinguished by radar. For example, it can pick up a tire laying in the road and warn the driver. Magna’s U.S. offices are in Michigan and that’s totally a Michigan thing.
The Icon Radar can also pick up stopped vehicles inside a tunnel, a pedestrian beside a guardrail as two separate items, and safe pathways on a multilane highway.
