Abstract: A general radar echo simulator hardware architecture based on PC and FPGA is proposed, which is a kind of PC+FPGA+D/A simulation system, and the simulator architecture has come to be a good choice with the development of PC technique and advanced chip field. The system is mainly based on a kind of PCI board which includes Virtex-4 FPGA and high performance D/A convertor with latest techniques and flexibility. Compared with traditional instruments, it is scalable, programmable and suitable for upgrading. The developed simulator has been tested and results show that the technical performance can meet the requirements of our application.
