S/C Band Harmonic Radar for Honey Bee Detection

Harmonic radar technology has been researched and developed for studying the foraging behaviour of honey bees. This work presents the development of a working prototype of a narrow-band harmonic radar system, at 2.5/5GHz, using off-the-shelf components to detect the presence of Indian honey bees. Based on empirical tests on the tag, we estimate the radar probability of detection and probability of false alarms as 88% and 0.3% respectively. The maximum detectable range for a monostatic configuration of the radar is 3.84 m.
