However, if a UAV is out of the visible range of the operator or many UAVs fly within a small region, a detector which can detect the obstacle and the altitude is required on the UAV. Compared with the optical and ultrasonic detectors, microwave/millimeter-wave radar provides a longer and wider detection range and can be operated in the environment without light. In addition to detecting to obstacle in front of the UAV, the microwave/millimeter-wave radar also can be used to detect the altitude of the UAV. In this project, the goal is to develop the low-power-consumption and high efficiency radio-frequency front-end integrated circuit for the multi-directional microwave/millimeter-wave radar UAVs.無人機雷達射頻積體電路UAVradarradio-frequency (RF)integrated circuit (IC)
