Abstract
A technique for observing foraging bumblebees with a 24 GHz continuous-wave Doppler radar is described. Upon departing from the colony, we discovered that foraging bumblebees accelerate briefly at a constant 9.8 m/sec2, resulting in a distinct, linear frequency modulated (LFM) radar return. By correlating this return with an expected LFM template, departing bumblebees could be identified and counted while arriving bumblebees and other environmental effects are rejected.
