Research of Radar Signal Processor Based on the Software Defined Radio

The paper addressed how to design the software radar signal processor based on the software defined radio structure, and discussed the reasons for using the DSP+FPGA and offered an insight into fix on the important parameters of software radio. Attention is concentrated on the construction of algorithm model, simulation the algorithm by Simulink, and some methods for algorithm and architecture mapping were discussed. The computer simulation of hardware model is provided; it changes the structure of hardware, and realizes the new function through the promotion or update of software. So the design and implementation of a velocity & distance-measuring radar signal processor based on the SR structure were studied. Evidences have shown that it especially suits the design of radar because of the similar structure and SR.
