摘要
天线增益外场测试的关键是提高增益测试精度。通过研究源天线高架测试场中直射和反射信号之间的合成关系,提出极值平均直射信号修正模型,给出了源天线高架测试场天线增益修正算法和测试方法。通过试验外场的测试,证明了模型的正确性。
How to improve the test precision of antenna gain is the key point for antenna gain test in the outfield. Through studying on the synthetic relationship between the direct and reflected signals in Source Antenna Overhead Test Range （SAOTR） , a direct signal correction model using the extremum average method is provide; an antenna gain correction algorithm and measurement method in SAOTR is presented. The antenna gain test in the outfield proves the validity of this model.
