Miniature Radar Altimeter Supports Sea-skimming UAV Test

Thursday, 20 December 2012 00:00

Roke Manor Research Ltd (Roke), a Chemring Group company, has supplied its Miniature Radar Altimeter (MRA) in a successful flight test of a sea-skimming UAV designed to mimic the threat of an incoming missile.

2012-mra-scrab.tnUAV Navigation, a developer of flight-control avionics for unmanned aircraft, led the test on a range used by the Spanish Navy. Roke's MRA Type 1 was integrated into its LCAP autopilot system, enabling the aircraft to accurately determine its height above the sea.

The flight test involved a SCRAB aerial target UAV, flying at cruise speeds only a few meters over the water which followed its flight path without the intervention of a human pilot.

Paul Webb, Unmanned Systems Business Sector Manager at Roke, said:

"UAV Navigation chose Roke's MRA as it remains the most technologically capable in its class. It has been developed for easy installation into all major UAV platforms, and provides outstanding capability at low-cost. Importantly for this particular test, was that the MRA was developed to meet the IP67 rating, which is essential when recovering the UAV from the surface of the sea."

Roke's lightweight MRA maximises payload and provides continuous accurate measurements in the most challenging flying situations such as misty or dusty conditions. This ensures missions can continue regardless of the environmental conditions.
