The Sampling Processing Transmission Of Radar Signal Based On SOPC Technology

Radar signal sampling, processing and transmission generally implement by FPGA, DSP and PCI joint structure. FPGA executes the pretreatment IF digital signal, and the DSP high-speed processing unit completes complex algorithm. The overall system works as master/slave mode with an industry personal computer through the PCI interface, which carries out the data transmission and storage. Such system architecture inherited the idea of radio software has good overall performance, but consumes much power.In this paper, considering the actual characteristics of the wild detection, a solution based on the SOPC technology is proposed. Signal sampling, processing and transmission are realized in one high-performance single-chip FPGA, which simplifies the circuit design and reduces the system power consumption. This paper introduces in detail the SOPC technology realization scheme and design method, describes the SOPC technology development environment, design tools and application processes provided by Xilinx Company and discusses the entire hardware structure of the system and all parts of the circuit realization principle. On this basis, the paper presents the embedded microprocessor hardware design specific process based on SOPC technology. A basic system including Ethernet, RS232, GPIO IP cores is constructed utilizing the BSB wizard tool. Then DDC customized IP core is attached to the OPB bus, importing to the basic system. We carry on IP parameter modification, editor the UCF file, and generate hardware bit stream to complete the system's microprocessor hardware design. In conclusion, the paper introduces the system software development environment, gives the procedures flow of the system, discusses the test method and proposes the research direction in the further.
