• ROBIN's 3D Flex system consists of a horizontal S-band radar, combined with a flexible Frequency Modulated Continuous Wave (FMCW) radar. The horizontal X-band radar identifies the presence and number of birds in time – including their location, height, direction, speed and route – up to 10 kilometres away, all around, day and night.

    The FMCW radar has three modes:

    • In the “Staring Mode” the radar stands still and ‘stares’ at a target. Traditional radars transmit a pulse while turning and then ‘listen’ to its echo. Robin’s FMCW radar has two beams. One is continuously transmitting and the other is continuously receiving
    • In the “Scanning mode” the antennas revolve around the horizontal axis continuously and creates altitude profiles based on all measured tracks in the beam. The angle of the coverage area can be chosen freely by rotating the radar around its vertical axis towards the particular area of interest. (Remotely configurable in a scheduler)
    • In the “Automatic acquisition mode” the antennas revolve around the horizontal axis continuously. When an alarm track is found (based on preinstalled and customer specific alarm algorithms), the radar automatically rotates towards that targets and gathers altitude information

    Of all available configurations, the ROBIN 3D Flex offers the most possibilities, including measuring the wingbeat pattern and frequency of a single target. Combined with other variables like reflection size and flight behaviour, this provides valuable input for distinction between species.

    This configuration is used both in civil aviation for wildlife management and in bird strike prevention at airports, as well as for monitoring birds in offshore wind farms and for field research.
