【Abstract】 In modern radar system, signal processing is becoming more and more important. Algorithm and software/hardware implementation platform is also kept improving continuously. The paper is according to the development of the signal processing system research of one kind weapon locating radar. It studies some critical technologies of the design and implementation of the signal processing system. For algorithm design, it discusses the algorithm flow of the weapon locating radar and the implementation method of corresponding algorithm, such as DPC, MTD, CFAR, etc. For system design, high-speed performance of FPGA hardware and flexibility of DSP software is combined very well. And it introduces one modular signal processor configuration based on DSP. The hardware and software platform of the signal processor is composed by the configuration. In terms of the requirement of system algorithm and operation time, one kind usual high-speed operation system based on TS201 processor is developed. The system has some character such as flexible modulation, high real-time, strong expansion etc.Simulation, debugging, trial and practical application of the developed signal processor shows that all specifications can meet requirements of the weapon locating radar. The signal processor has been successfully used in the weapon locating radar.更多还原
