| Abstract: | To digitize and acquire the muhi-channel range radar signal, a multi-channel data acquisition system was designed. This system was based on FPGA and USB2.0 interface, several digital logic control modules were constructed in FPGA to control the AD conversion of analog signal and data cache. The acquired data was sent from the data cache to PC through the USB2.0 interface. All these designs achieved a complete multi-channel data acquisition, storage and transmission system. It can acquire 8 channels range radar signal and its highest single-channel sample rate up to 250KSPS. With the help of USB2.0 interface chip, all acquired data can be send to PC in time for further digital signal processing. |
