Abstract:

To address the need for constructing complex electromagnetic environments in hardware-in-loop radio frequency simulation testing, this study investigates signal modeling, generation, and modulation methods for radar and communication. Based on RFSoC chip, a reconfigurable signal excitation generation device is proposed, featuring multifunctional and compact signal excitation capabilities. Test results demonstrate that the reconfigurable device can generate ultra-wideband radar and communication signals according to set parameters, or output pre-recorded signals via playback, providing robust support for building complex electromagnetic environments in indoor settings.
