The invention discloses a full-airspace array antenna GT value consistency measurement method based on an unmanned aerial vehicle, and the method comprises the steps: employing the unmanned aerial vehicle to mount a measurement and control responder and an unmanned aerial vehicle RTK module, and enabling a measured antenna to receive and measure the signal-to-noise ratio of a signal transmitted by the measurement and control responder in a full-airspace range; and calculating to obtain a mean value and a mean square error of the G/T values of the tested antenna at different spatial positions, namely the G/T value and the consistency of the antenna to be tested. According to the invention, the problem in the prior art that the requirements of checking and evaluating the G/T value and the consistency index of the whole-airspace array antenna cannot be met in terms of measurement method and precision is solved.
本发明公开了一种基于无人机的全空域阵列天线GT值一致性测量方法,采用无人机挂载测控应答机及无人机RTK模块,被测天线在全空域范围内接收和测量测控应答机发射的信号信噪比,计算得到被测天线实际在不同空间位置G/T值的均值和均方差,即为待测天线的G/T值及一致性。本发明解决了现有技术中存在的在测量方法和精度上,无法满足考核和评估全空域阵列天线G/T值及一致性指标的要求的问题。
