摘　　要：通过对佘山站模拟式微波辐射计的改进,摒弃了传统的绘图仪,提高了数字化和自动化程度,降低了劳动成本。系统设计以ARM核微控制器和FPGA可编程逻辑器件为核心,外接存储器和其他外围电路,很好地实现了数字自动零点补偿和数据采集功能,使得硬件体积更小、功耗更低、功能更多、可扩展性更强。The design of digital microwave radiometer at Sheshan station has realized the digital and automatic function and reduced the cost of labor. The system design based on ARM core microprocessor and FPGA programmable logic chip containing some memory units and periphery component has realized the automatic zero compensation and data acquisition as well as PC video displaying. Consequently,the volume of the hardware is smaller; power consumption is lower; the functions are mightier and the expansibility is stro...
