摘要
为了设计一个适用于P波段雷达天线测试的天线测试场,针对P波段雷达天线在室外远场测试时较难控制的地面反射问题,采用几何光学方法,结合具体实例,对斜距场法、等高场法、脉冲测试法和地面反射场法几种室外远场测试方法进行了分析;根据分析结果并结合实际地形条件,选取了地面反射场法作为测试方案;应用FEKO软件对测试场静区处的幅度和相位进行了仿真,得到该场地静区处的合成场能够满足天线远场测试要求的结论。
In order to design an antenna testing range for P-band radar antenna measurement, in view of the difficulties about ground reflection control of P-band radar antenna in outdoor far field measurement, several far-field measurement methods including slant range method, elevated range method, pulsed measurement method and ground reflection range method are analyzed by using geometrical optics approach. The ground reflection method was selected as the test range solution by considering analysis results and practical topographic conditions. The amplitude and phase of the quiet zone were simulated by applying FEKO. It shows that the synthetic range in the quiet zone can satisfy the requirements on antenna far-field measurement.
