Abstract
A radar system for detecting objects can comprise an RF transmitter that emits RF light and at least one light source that emits visible light in response to the RF light detecting the presence of an object. The system can include a dielectric lens that collects and focuses the RF light. The dielectric lens can also include features that collect and scatter the visible light.
