Millimetre-Wave Radar for Foreign Object Detection

    The Challenge

    Wave Tech, a Korean-based RF signal technology company, required a radar-based Foreign Object Detection (FOD) system for airport runways, capable of rapidly detecting small debris in all weather conditions.

    FOD is an important security, safety and quality control in any aviation environment; where small debris, loose objects and wildlife has the potential to cause damage to airport equipment and delays to runway operation.

    Our client’s vision was for a low-cost solution that could be easily deployed into the market without compromising the high-performance necessary for reliable operation.

    The Approach

    Our recent studies into millimetre-wave radar enabled us to produce a dual fixed and mobile antenna solution capable of detecting objects and movements from a fixed radar at 400 m range.

    Plextek designed and mounted a fixed antenna along the runway for stationary scanning and detection. A mobile system, a 300 mm antenna for rapid rotation, was also delivered and was designed to be mounted onto the roof of a vehicle to scan the runway while moving.

    Enhancing the situational awareness of the technology required utilising advanced signal processing algorithms to discriminate between wanted and unwanted signals and to separate detection of targets in close proximity to each other.

    The Outcome

    Our mm-wave radar solution was able to deliver 100% target illumination results in early-stage development tests, displaying accuracy and detection equivalent to a single fixed antenna.

    The advanced design enabled our client to produce highly accurate FOD results with reduced deployment costs and time to market.
