商业蓝莓的大部分授粉是由数百个蜂巢的蜜蜂进行的。提出了一种用于监测蜂箱健康状况和生产力的活动传感器。使用低功率 5.8 GHz 多普勒雷达观察在蜂巢入口附近飞行的蜜蜂。评估谱矩、熵、多样性和均方根 (rms) 功率，以识别觅食蜜蜂并量化觅食活动水平。理论和实验结果证明熵、多样性和均方根功率是相关的，并且是蜜蜂活动的同等有效的指标。特别地，可以在没有相干接收器和信号处理的情况下测量多普勒信号的均方根功率。这种类型的测量适合于蜜蜂活动传感器的第二种、相当便宜的实施。
Most pollination of commercial blueberries is carried out by honeybees from hundreds of hives. An activity sensor for monitoring the health and productivity of beehives is presented. Honeybees flying near the entrance of a beehive were observed with a low-powered 5.8 GHz Doppler radar. Spectral moments, entropy, diversity, and root-mean-square (rms) power were evaluated to identify foraging bees and to quantify the level of foraging activity. Theoretical and experimental results are presented to demonstrate that entropy, diversity, and rms power are correlated and are equally valid indicators of bee activity. In particular, the rms power of the Doppler signal can be measured without a coherent receiver and without signal processing. This type of measurement lends itself to a second, considerably less expensive, implementation of a bee activity sensor.
