Research on Broadband Complex Electromagnetic Environment Signal Simulation Technology Based on Channel Reconstruction

Based on an efficient channelized structure, this research focuses on channelized reception, channel reconstruction transmission, and baseband signal generation. A broadband complex electromagnetic signal simulation method is proposed, and a design of the simulation scheme for broadband complex electromagnetic signals is implemented using domestically produced devices. Through simulation and experiments, it is demonstrated that this method can achieve multi-target simulation capability in a complex electromagnetic environment with an instantaneous bandwidth of 4 GHz. It can also be extended for applications in radar target simulators ranging from 0.8 GHz to 18 GHz.
