Very high frequency (mm wavelength) anti-collision RADAR system uses a very narrow pencil beam to:

• detect the presence and speed of obstacles in front of the UAV
• detect fine horizontal wires, if a horizontally polarized mm wave beam is used
• detect the altitude (radio altimeter function) and confirm the attitude of the UAV
• determine the ground speed of the UAV itself
• “see” through fog, cloud and rain

For the very high frequency millimetre wave RADAR system, we apply the most recent developments in automotive driver safety support, such as this 77 GHz RADAR system from Hitachi. The demanding cost requirements and relatively high volume production generally associated with the automotive industry, suggest a very cost competitive part.
