To resolve problems in simulation training of electromagnetic spectrum monitoring equipment,a new method of designing electromagnetic spectrum monitoring & training system is presented,which combines physical monitoring system and virtual simulation. The system realizes the effective reception of the real environmental electromagnetic signal using the working principle of the full digital intermediate frequency receiver. Two kinds of monitoring antennas are simulated through HFSS,which can be used in ultrashort wave and microwave frequency bands. The method of multi-thread parallel processing is proposed to improve the scanning rate effectively. And the training of electromagnetic signal directionfinding is realized by virtual simulation. As an effective means for equipment teaching,it improves the real sense and efficiency of equipment operation training with low cost.
