Design and Implementation of Satellite Frequency-Spectrum Monitor System Based on LabVIEW

随着微波技术的广泛发展，使用静止轨道卫星组网的卫星应用系统面临着频带日益拥挤、自然和人为干扰日益增多的问题，所以有必要对卫星信号进行频谱监测，及时发现频带内存在的干扰，以便采取相应措施将影响降至最低。为达到此目的，文章给出了一种基于LabVIEW软件的卫星频谱监测系统方案设计及其实现。实践证明，该系统能对静止轨道卫星信号进行频谱监测，能在一定程度上检测出卫星信号中存在的干扰信号，提高了卫星应用系统自身性能监测判断能力。

With the wide development of the wavelet technology, the GEO satellite organized application system is faced with the problems aroused by the jam-packed bands and increasing interferences, which makes the frequency-spectrum monitoring and interference detecting duly necessary, and then, it is possible to minimize the influence by taking action accordingly. An implementation of the satellite frequency-spectrum monitor system based on LabVIEW is presented in this paper. The experimentation has proved that this system is able to monitor the satellite frequency-spectrum, as long as to detect the interference infused in the available satellite signal, which will improve detection and estimation ability of the satellite application system.
