Design of a Two-channel Ultra High Frequence Data Acquisition System Based On FPGA

In this paper, design and realization of a two-channel ultra high frequency data acquisition system is introduced, capable of up to 1 Gsps sample rate, 8 bit resolution. With the large scale FPGA chip from Xilinx Inc, we can realize sample data receiving and digital signal processing. This system is flexible to extend and works steadily, so it can be used in such radar system as SAR which needs wideband signal sampling
