The concept and connotation of complex electromagnetic environment are clarified. Combined with the characteristics of equipment detection, the classification method of detecting electromagnetic environment with frequency equipment is put forward, and then the object of detection of electromagnetic environment is determined. The feasibility of electromagnetic environment construction in anechoic chamber is analyzed. According to the requirement of electromagnetic environment effect test of electromagnetic equipment for frequency equipment, a hardware-in-the-loop simulation system based on ADS and Agilent89600 software and test instruments was developed. An electromagnetic environment building system and electromagnetic environment evaluation system were set up in anechoic chamber. Finally , The selection principle of testing the evaluation index of electromagnetic environment and the evaluation index system based on the performance of electromagnetic signal are emphatically discussed.
