Bird Strike Prevention Radar

Bird Strike Prevention Radar

Kelvin Hughes collaborates with specialist solution providers for applications that require avian and wildlife radar, which is a unique and niche area of radar detection techniques. The SharpEye™ radar integrates easily with a mobile or static system equipped with antenna and tracker system for the detection of birds or bats.

Typical environments requiring radar as the primary sensor is bird strike alert and avoidance systems at civil, military and non-permanent airfields, airports, and approach and take off flight paths. The radar enables the local airspace operator to identify large birds and flocks of birds that are on a path or have the potential to cross or interrupt air traffic. Action can then be taken by use of automatic bird scare systems or for other manual actions to be initiated.

Other Avian applications include the monitoring, mapping and analysis of migratory birds and bird protection and scaring in hazardous areas such as the Canada Tar Sands.

In collaboration with the market leaders in avian detection using radars, Kelvin Hughes has provided SharpEye™ coherent radar transceivers and antennas for:

  • Monitoring the movements of birds
  • Bird strike avoidance radar system at Bagram Airfield, Afghanistan
  • Bird strike avoidance system at Boston Logan International Airport
  • Bird Strike avoidance system at Riga Airport in Latvia
  • Bird scare system for migratory birds passing through the Tar Sands in Canada

SharpEye™ radar technology through a clever combination of radar techniques is designed to provide the best performance in all conditions whilst also providing the flexibility to be optimised for specific detection needs.

Solid state radar ensures extremely high reliability and low through life costs:

  • No magnetron - minimal routine maintenance requirements
  • High MTBF - high availability and reliability
  • Upmast and mast mounted transceivers - reduced waveguide - reduced signal loss - reduced infrastructure and operational costs
  • Frequency diversity
  • User selectable frequencies to ensure interoperability

SharpEye™ transmits a low power patented pulse sequence, which enables short, medium and long range radar returns to be detected simultaneously.

Doppler processing of radar returns provides coherent information concerning target velocity (radial) and enables the detection of very small and slow moving objects and targets with a low Radar Cross Section (RCS). Through a series of electronic filters it is able to distinguish between the targets of interest and sea, rain and land clutter.

Other differentiating technologies include Moving Target Detection (MTD) providing enhanced clutter suppression at the Doppler processing stage and pulse compression of the return signal enabling a low transmit power providing efficient use of the radar. Other Doppler radars may employ less advanced techniques such as Moving Target Indication (MTI), which do not take full advantage of the radial velocity information.
