摘要
目前,辐射场均匀性主要采用单点多次测试的方式来实现,该方式将不可避免地引入因辐照信号自身时变特性带来的测量误差;此外,单点多次测试极大地增加了测试时间、测试效率低下。为解决这些问题,本文设计了一种可实现一次多点测试、测试区域可自动调节的装置,仿真表明:该装置可满足500mm×500mm^1500mm×1500mm区域辐射场9点均匀性测试;在此基础上,在1000mm×1000mm测试区域,针对1.35GHz和2.88GHz两个频点开展了实验验证,实验表明:设计的测试装置可满足辐射场均匀性9点自动测试要求,大幅提高了测试效率和自动化程度。
The uniformity of high-intensity electromagnetic radiation field is mainly realized by multiple tests at a single point presently,which will inevitably lead to measurement errors due to the time-varying characteristics of the radiation signal itself.Moreover,the method of multiple tests at a single point greatly increases the test time and lowers the test efficiency.To solve these problems,a device realizing multi-points test was designed.The test area can be adjusted automatically.The simulation results show that the device can meet the 9-point uniformity test of radiation field in the range of 500 mm×500 mm-1500 mm×1500 mm.In the 1000 mm×1000 mm test area,the experimental verification was carried out for the two frequency points of 1.35 GHz and 2.88 GHz.The experiment shows that the designed test device can meet the 9-point automatic test requirement of high-intensity radiation field uniformity,which greatly improves the test efficiency and automation.
