Abstract :
Hardware design methods for MIMO (Multiple-input multiple output) UWB (Ultra wideband) radar are presented. The MIMO-UWB radar system mainly consists of two transmitting antennas, four receiving antennas, two impulse generator, sample-and-hold, AD converter, and data acquisition subsystem base on FPGA. All these modules are designed and realized. Additionally, the designed system supports four equivalent time sampling channels with 50GS/s sample rate. Finally, we proved the feasibility of the designed system through closed-loop testing.
