网络无线侦察接收机软件系统的设计和实现

Design and implementation of the wireless surveillance receiver software system

为兼容无线电监测网传输协议(RMTP),实时监测无线电信号并测量其频率、带宽等技术参数,无线侦察接收机软件系统通过网络接收硬件采集的无线电信号,使用经典功率谱估计方法对其进行频谱分析。系统用户界面采用跨平台GUI库CodeBlocks+wxWidgets进行开发,使用二维图形库wxMathPlot开发画图模块,将测量和分析的结果以频谱图的方式展现给用户。分析了系统的基本架构,wxWidgets库的使用方法,经典功率谱估计算法,重点讨论了如何解决网络传输过程中可能遇到的"粘包"问题。

In order to be compatible with RMTP, and real-time monitor the radio signals and measure the frequency, bandwidth and other technical parameters, the software system of wireless surveillance receiver receives the data from the hardware through the internet, and uses the classical power spectrum estimation method to do the spectral analysis. The system utilizes the cross-platform GUI library CodeBlocks ＋ wxWidgets and the two-dimensional graphic library wxMathPlot to design the user interface and the painting module respectively. Finally, this system shows the results of the measurement and analysis on GUI. This paper analyzed the basic architecture of the system, the using method of wxWidgets, and the classical power spectrum estimation method. It focused on how to deal with the ＂stick pack＂ problem which maybe encountered during the network transmission.
