| Electromagnetic environment is the summation of all electromagnetic phenomena. When equipment (subsystem or system) execute stated mission on the special place, it could encounter all kinds of usable or unusable electromagnetic disturbance, their amount & type & distributing are difference in frequency or power in different time. Electromagnetic environment testing is to know the information of received signal, capture and record electromagnetic frequency, calculate or estimate Electromagnetic source's characteristic. Refer testing report; make the primary conclusion and relevant suggestion.Through designing and developing the programming wave band switch amplifier, developing the programming control platform,writing the testing software, using frequency spectrum analyzer & modulation domain analyzer and numeric oscillograph in existence. The testing system is build, which can record and analyze the space signal frequency spectrum, propagation way and modulate type in frequency domain, time domain or modulation domain.The width-frequency band and mobile Electromagnetic environment testing system can test the Electromagnetic environment in suitable place and time, obtain abundant and detailed datum, Located electromagnetic interference source, so it can provide technical proof for manager's decision-making such as choosing the suitable place building control station, satellite and missile EMC testing.In conclusion, Electromagnetic environment testing system can enhance our Elecromagnetic environment testing capability, improve equip reliability level, it is important for the department which concerns the Electromagnetic environment. |
