【摘要】 文章针对天气雷达缺乏远场标定能力的现状，提出利用无人机有源标定仪开展天气雷达远场标定的方案。通过给出无人机有源标定仪开展天气雷达远场标定试验的测试项目与条件，完成了对雷达天线、发射通道和接收通道的标定测试，试验结果符合相关技术要求。后期将对标定仪做进一步改进和完善，以期更好地满足雷达标定业务需要。更多还原

【Abstract】 This paper proposed a scheme for far-field calibration of weather radars by using unmanned aerial vehicle(UAV) active calibrators, in response to the lack of far-field calibration capabilities of weather radar.By providing the test items and conditions for the UAV active calibrator to carry out far-field calibration test of the weather radar, the full-link test of the radar antenna, the transmitting channel and the receiving channel was completed.The test results meet the relevant technical requirements.In the future, the calibration instrument will be further imporved in order to better meet the needs of radar calibration business.更多还原
