摘　　要：增强型发射天线作为高精度地基授时系统的重要组成部分,其测试方法也同样至关重要。由于该发射天线体积大,造价高,结构复杂等原因,对正在建设或已建设完成的天线系统进行详细测试难度较大,因此通过缩比模型的实验方法进行初步测试,既可以对发射天线的各项参数进行初步设计,也可以根据工程的需要进行相应调整,从而为实际建设提供实验基础,并提前解决和分析可能遇到的各种问题,更好地服务于高精度地基授时系统的建设。The test method of the enhanced transmitting antenna, which is an important part of the Highprecision Ground-based Time Service System, is very important. Due to the large size, high cost and complex structure of this antenna, it is difficult to test the antenna system which is under construction or completed in detail.Therefore, the preliminary test is carried out using the experimental method of reduced scale model. With the help of this method parameters of the transmitting antenna can be preliminarily designed and adjusted according to the needs of the project. It provides the experimental basis for the construction, and solves and analyzes various possible problems in advance, and serves the construction of the High-precision Ground-based Time Service System better.
