Today’s leading advanced RADAR sensors, pioneered by military aircraft, are now becoming affordable for automotive use. This provides incredibly fine object resolution in 3D, protected by hardened security systems that resist interference and jamming. This approach also allows us to use radar cross sections to identify targets and predict how they will move/behave. This presentation explains how radar is increasingly becoming an essential sensor for autonomous driving and will illustrate the features that combined with other sensors or even on their own will make autonomous vehicles safer.
