Now a University of Canterbury (UC) research team is pooling its expertise across the
College of Engineering to hone new tag-and-track technology that could transform our
understanding of the insect world. Co-leading the project are School of Forestry senior
lecturerandforestentomologistDrStevePawsonandsignalprocessingexpertDrGraeme
WoodwardoftheWirelessResearchCentre.
¡°Wehavefabricatedabout20testharmonicradartagstodate,allowingustoexperiment

Being developed alongside these tags is associated ¡®unmanned aerial vehicle¡¯ (UAV) or
dronetechnology.
¡°The idea is that we could activate a swarm of UAVs that would be able to track and
followtheinsectinrealtime,¡±explainsDrPawson.
Unlikepreviousharmonicradartrackingfacilities,thetransmittersbeingfine-tunedforthis
project are designed with mobility in mind and to operate with a much lower power
requirement. This allows informationto be gathered in complex landscapes andat greater
distancesatamuchlowercost.
Researchers hope to commence field testing in 2023, starting with ground-based insects
before tackling the complexities of tracking insects in flight. This exciting research has
