Abstract:

This paper designs a signal processor based on FPGA+DSP system.There are three core units working with each other to achieve target detection and orient identification about multichannel doppler signals.The processor carries out the functions of target detection based on frequency domain,and realizes orient identification on eight quadrants,which improves the fuze-warhead coordination efficiency.Hierarchical design ensures real-time and flexible signal processing with massive scalability.

Key words: multi-core units;orient identification;CA-CFAR;real-time
