中文摘要:
      目的 为满足吸波涂层在装机条件下雷达反射率原位测量的迫切需求,提出一种基于天线近场测试的雷达反射率原位测量技术。方法 设计小型化超宽带天线、收发去耦结构以及屏蔽罩,构建原位测量探头,并与微波扫频模块和数据处理模块集成,研制出雷达反射率手持式宽频测量仪并。结果 经对比验证,在−17~0 dB反射率范围以及2~18 GHz频率范围内,该测量仪测量结果与弓形系统测量结果偏差小于1.5 dB。结论 该测量仪适用于厚度为1.5 mm以内已涂覆涂层雷达反射率的准确测量。
英文摘要:
      The work aims to propose an in-situ measurement technology of radar reflectivity, which is based on the antenna near-field measurement, so as to meet the urgent requirements for in-situ measurement of radar reflectivity of microwave absorbing coatings under installation conditions. A miniaturized ultra-wideband antenna, a decoupling structure, and a shielding cover were designed, and an in-situ measurement probe was constructed. By integrating the probe with a microwave frequency scanning module and a data processing module, a handheld broadband radar reflectivity measuring instrument was developed. Through comparison and verification, the deviation of its measurement result from the arch system was less than 1.5 dB in the reflectivity range of −17 to 0 dB and the frequency range of 2 to 18 GHz. The instrument is suitable for accurate measurement of radar reflectivity of coatings with a thickness of less than 1.5 mm.
