摘要
设计了一种采用FPGA+DSP系统框架的信号处理机,由3个核心处理器协同工作,共同完成多通道多普勒信号的目标检测和方位识别等功能。该信号处理机在实现频域目标检测功能的同时,实现了8象限的方位识别功能,能够提高引战配合效率。多处理器的分层设计保证了该信号处理机的实时性和灵活性,是一个具有较强可扩展性的信号处理开发平台。
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.
