Speed control radar

Belongs to:
Radar system
Description:

Speed control radar is used for velocity measurements of vehicles ashore. As the electromagnetic waves emitted by a radar device are simply reflected by an approaching vehicle, speed control radars are unambiguously primary radar systems.

Frequency ranges:
  • 9–35 GHz (from the X band up to the Ka band)
Type of field:
electromagnetic
