Objective To develop a high performance digital signal processor suitable for the characteristics of quasi continuous wave tracking radar. According to the characteristics of quasi-continuous wave radar, the traditional analog dual channel sampling is replaced by intermediate frequency sampling. In the design of processor, Instead of a dedicated DSP, and the parallel processing structure used in the results of this method compared with the traditional simulation method, the image rejection ratio can be increased nearly 1 times Conclusion Intermediate frequency sampling technology for quasi-continuous wave radar system In addition, the use of general-purpose DSP as a processor Hardware platform, all of the signal processing functions implemented in software to simplify the system structure and increase flexibility, is a promising solution for processor implementation
