现代雷达要求雷达信号处理机中的电路系统具有信号处理能力强、体积小、工作模式灵活多样等特点，而当前雷达工作模式切换方式无法满足这种要求。为此，利用FPGA的动态可重构技术，提出了一种动态可重构的雷达工作模式切换方法，并以SOPC方式进行系统实现。实现结果表明，该切换方法与其他三种方法相比，减小了设备硬件资源，提高了切换的实时性，满足了雷达信号处理的需要。

The circuits and systems of signal processor in modern radar systems are required to be of high signal processing ability, small volume, flexible operational modes and etc., while the current switching ways of radar operational modes are unable to meet this requirement. This paper proposes a switching way of radar operational modes with dynamic reconfiguration using the FPGA dynamic reconfiguration technique, and carries out the system implementation by way of SOPC. Implementation results show that the switching method can reduce the hardware resource of the equipment, boost the switching in real time and meet the demand of radar signal processing, compared with the other three methods.
