摘　　要：设计实现了一种超宽带步进频率连续波探地雷达数字信号处理机。处理机以TS201芯片为处理核心,采用了分布式存储和独立总线结构,利用link口实现处理器间和板间高速数据交换。基于处理板结构设计实现了信号处理算法流程。该步进频率探地雷达信号处理从流程上划分为数据整合与回波预处理、合成孔径成像、图像增强与杂波抑制和跟踪检测四个模块,可实时输出雷达图像和检测结果。该处理机成功地应用于某探地雷达系统,运行稳定。The digital signal processor（DSP） of a stepped frequency continuous wave ground penetrating radar is implemented.The DSP board consists of multiple TS201 chips with independent memories and local buses.The link ports are used for high speed data transfer among different boards and chips.A signal processing flow chart is designed and implemented based on the DSP board.The flow chart consists of pre-imaging data processing,synthetic aperture imaging,clutter suppression,target detection and tracking.Both radar images and target detection results can be provided.The digital signal processor worked well in a ground penetrating radar.
