摘　　要：主要讨论了电磁兼容检测领域和无线电射频检测领域。给出了频率范围为30~1000 MHz时,在半电波暗室测量的辐射发射(骚扰)电场强度和在全电波暗室测量的等效全向辐射功率(EIRP)之间的理论推导关系,说明在理论的基础上,电场强度与等效全向辐射功率的测量值是可以相互转换的,为电磁兼容领域电场强度的测试考核和无线电射频的发射功率的测试提供了相应的参考,同时可以缓解半电波暗室和全电波暗室转换的测试压力,节省了搬移吸波材料所产生的人工成本和避免了吸波材料的损坏。The field of electromagnetic compatibility detection and radio frequency detection is discussed.The theoretical derivation relationship between the radiative emission(disturbance)electric field strength measured in the semi anechoic chamber and the equivalent isotropically radiated power measured in the full anechoic room when the frequency range is 30 MHz to 1000 MHz.It shows that on the basis of theory,the measurement of electric field strength and equivalent isotropically radiated power can be converted to each other.Corresponding references for the test and assessment of electric field strength in the field of electromagnetic compatibility and the emission power of radio frequency are provided.At the same time,the test pressure of semi anechoic chamber and full anechoic room conversion is relieved,the labor cost caused by moving absorbing materials is saved and the damage of absorbing materials is avoided.
