摘要
为了满足高分辨率微波成像等大数据量远距离微波测量的需求,设计并实现了一个基于以太网的分布式微波测量系统。文中给出了系统组成和各部件的作用。该系统的关键部件是一个数字中频接收机,利用DSP和FPGA实时获取幅度和相位数据,从而提高了测量速度和灵活性。文中也描述了硬件和软件的实现。
A distributed microwave measurement system based on Ethernet was designed and implemented in order to meet the requirements of mass - data remote microwave measurements, such as high resolution microwave imaging. The system constitution and the action of its components are given. The key component of the system is a digital intermediate frequency receiver employing DSP and FPGA to obtain amplitude and phase data in real - time, which improves measurement speed and flexibility. The implementations of hardware and software are also described.
