ABOUT
The radar unit is not currently active but operates two different types of radars, namely the Vertical-Looking Radar (VLR) and Harmonic Radar (HR).
The Vertical radar has been designed to continually monitor the movement of high-flying insects between 150m and 1200m above ground level in England.
The Harmonic radar has been designed to study the behaviour of low-flying insects over relatively large spatial scales. A transponder weighing just a few milligrams fitted to the thorax picks up the interrogation radar signal and immediately emits a signal at a different frequency which is received by the radar.
