摘　　要：微波辐射计是测量目标微波辐射特性的被动式遥感器。微波辐射计数据采集系统根据系统工作模式的选择,利用模数转换器以及可编程逻辑器件FPGA对信号分别进行量化和控制,再通过RS232接口和以太网口与远程计算机系统进行通信,完成对信号的采集和数字化处理。本文基于Qt平台开发上位机软件,依赖第三方串口类QextSerialPort和自带的QUdpSocket类,完成了数据的传输、显示和存储功能,再通过解析数据包提取目标的微波极化信息,利用QwtPlot控件完成二维曲线和三维散点图的绘制。该软件提高了数据采集和处理的效率。Microwave radiometer is a passive remote sensing device that measures the target’s microwave radiation characteristics.According to the choice of system operating mode,microwave radiometer data acquisition system uses analog-to-digital converters and programmable logic device FPGA to quantify and control the signal,and then communicates with remote computer system through RS232 interface and Ethernet port,completing signal acquisition and digitization.This article develops user-control software based on the Qt platform,relying on the third-party serial port class QextSerialPort and own QUdpSocket class,completes the data transmission,display and storage functions,and then extracts the target's microwave polarization information by parsing the data packet,using the QwtPlot control to complete Drawing of 2D curves and 3D scatter plots.The software improves the efficiency of data acquisition and processing.
