The research topics include acquiring the bees suffered by colony collapse disorder (CCD) and the tracing of bees. To support the research of acquiring CCD bees, we will modify the beam shape of the existing radar system from a pencil beam to a fan beam. As a result, we can achieve the requirement to search the targets at different heights at the same time. On the other hand, we will develop portable harmonic radars for the search of the target in short distance. To support the research of bee tracing, a phased array will be developed to overcome the limitation of the motor scanning speed. Moreover, the required time to calculate the distance will also be reduced with the implementation of the signal processor in the high speed FPGA. In the first year, the improvement of the existing radar system for acquiring CCD bees research will be accomplished. The phased array radar will be finished in the middle of the third year. We will first develop small phased array radars, and then integrate the small phased array radars to a large phased array radar system.諧波脈衝雷達扇形波束相位陣列天線Harmonic pulsed radarfan beamphased array antenna
