摘　　要：通过总结传统辐射杂散测量的经验,结合18~40 GHz频段无线电信号的传输特性,提出了利用辐射杂散替代法在全电波暗室的条件下测量该频段辐射杂散骚扰的方案。主要介绍了18~40 GHz频段辐射杂散测试系统的组成、布置、校准和测量方法,为该频段辐射杂散的准确测量提供了一定的参考。By summarizing the experience of traditional radiation spurious measurement,combined with the transmission characteristics of radio signals in the frequency band of 18~40 GHz,a scheme of using the radiation spurious substitution method to measure the radiation spurious disturbance in this band under the condition of a full anechoic chamber is proposed.The system composition,arrangement,calibration and test method of radiation spurious test in the frequency band from 18~40 GHz are introduced,which provides some guidance for the accurate measurement of the radiation spurious in this frequency band.
