Abstract
There is provided a radar system that includes an emitter system (e.g., an antenna), configured to emit electromagnetic pulses and detect electromagnetic pulses, and a reflection target, placed opposite the emitter system. The emitter system and the reflection target define an area of interest. A controller is configured to identify a reflection from the reflection target and, if the reflection is not identified, to stop sending a radar check signal. The radar system may be part of a warning horn control system, where the radar check signal is used as a control input for activating a warning horn.
