Fixed Wing

Autonomous Landing Guidance (ALG), or Autonomous Airborne Landing Capability (AALC), is designed for zero height, zero visibility landing. It has been extensively trialled in the USA on both military and commercial aircraft and, as a result of the successful programme, aircraft equipped with ALG are cleared to land in 0,0 visibility conditions at any airfield in the United States.

The system produces a real beam image of the airfield which looks the same in the radar domain whatever the prevailing weather conditions.

The ALG clearly reveals airfield features and is particularly important in foggy conditions by maintaining runway capacity and aiding taxiing so that the airport can continue to operate without the cancellation of flights.

The ALG uses a derivative of the mmW RF seeker with a replacement antenna and different software and is generally mounted in the radome of the aircraft.

Rotary

Helicopter landing in dust or sand (brown-out conditions) is highly dangerous, especially where the dust is particularly fine and pervasive. The mmW RF seeker hardware architecture can readily be adapted to provide pilots with situational awareness even in the worst conditions. The device is compact and lightweight yet is available virtually off-the-shelf.

Commercial Security

A rapid throughput security turnstile system incorporating an imaging radar, based on seeker hardware but with a different antenna and software, monitors personnel for weapons etc. Applications for this device include monitoring people entering :

  • Sports stadia (e.g. Olympic Games)
  • Underground / Metro
  • Airport security
  • Sensitive buildings

In order to achieve fast crowd throughput, the design objective is to use turnstiles similar to current standards and for the scan to be completed in Fixed Wing
