Design of a VHF Background Signals Simulator
Xie Jian-yong · Radio Engineering of China · 2009
In the world today,electromagnetic environment is very complex,including not only military radio and radar signals,but also civilian radio communications signals.We are concerned about the issue how to verify the communications equipment performance in a complex electromagnetic environment.A solution for a VHF background signals simulator is presented,simulating the complicating electromagnetic environment.The key technology and implementation method are discussed,with emphasis on the technology of digital frequency synthesizer,the TH/FH control and the DDS.Combined Interference of the transducer is analyzed.The design method for practical project is provided.
