A Kind Of Universal Signal Processing Module Design And Implementation Based On FPGA

In recent years, the Programmable Logic Device developed rapidly, especially the FPGA, which not only realized miniaturization, low power consumption and high reliability of the signal processing machine, also as universal signal processing module'flexible design, which based on FPGA, it is replacing ASIC on the market. FPGA is a kind of semi-custom integrated circuit, designers can completely control the design process, without any actual integrated circuit manufacturing equipment. Even though the radar signal processor with DSP processing core has been widely used, but its drawback is that real-time is not good, FPGA can solve this problem. Now FPGA develop rapidly, most existing FPGA integrated DSP module. The operability of FPGA as processing core used in universal signal processing module is strong.Based on radar signal processing demand, a universal signal processing module was designed and completed by author. The module uses a high-capacity FPGA as the core of signal processing, uses FLASH and SDRAM as external storage, uses SCM as bridge between FPGA and Computer. Through serial port, the designer can real-time debug and monitor.In order to complete this topic, the following aspects were studied in the dissertation.Firstly, analyze the characteristics of Radar signal processing detailed, we gain characteristics, processing method and project implementation of Pulse Compress, MTI/MTD and CFAR. What's more, we have a view of the advantage and disadvantage between different methods.Secondly, according to the characteristics of Radar signal processing, we have finished FPGA and other chips selection through simulation. We have completed schematic and PCB production in the software of Altium Designer 6.9, and also completed software interface design between FPGA and FLASH , SDRAM in the software of QuartusII 9.0.In the end, we introduce DA algorithm, and elaborate on programming of the Pulse Compression as well as process implementation on Universal signal processing module based on DA algorithm.
