基于DSP和ARM的穿墙探测雷达数据处理终端设计

Design of Data Processing Terminal for Through-wall Detecting Radar based on DSP and ARM

提出了一种基于DSP+ARM嵌入式双处理器平台的雷达数据处理终端设计方案。详细阐述了该数据处理终端系统的软硬件结构、各模块的工作机制以及DSP+ARM平台中双口RAM数据接口电路设计。实践证明,系统中DSP模块和ARM模块能较好地配合协同工作,完成雷达回波数据的实时采集、定位算法处理、目标信息显示以及系统控制等功能。

This paper presents an embedded double-kernel platform based on DSP and ARM used in the radar data processing terminal.The system structures and the module workflows are described,and the design of the data traffic interface based on high-speed dual-port RAM for DSP and ARM is introduced.The practices prove DSP cooperate with ARM work well in real-time echo acquisition,localization algorithm processing,real-time display of the target＇s orientation information and system control.
