摘要
传统无线电频谱监测系统监测功能复杂,造价昂贵,适合专业使用,对于应用要求不高的场合往往使用频谱分析仪进行代替使用,但存在监测效率不高和无法记录的问题,针对该问题,设计了一套基于Labview的频谱监测系统,实现了基于单类支持向量机模型的频谱智能检测、瀑布图和荧光图态势显示,以及实时记录与回放等功能;实验结果表明,频谱监测效果较好,具有推广应用价值。
The function of traditional spectrum monitoring system is complicated, expensive, and suitable for profession to use, and it can be replaced hy a spectrum analyzer when the monitor request is not high, but the problem is that the monitor efficiency may be inefficient and it can＇ t record the spectrum. Aiming at this problem, this thesis designed a new spectrum monitoring system based on I.abview soft ware, and implemented the function of automatic detection of a signal spectrum hased on the model of one class support vector machine , displaying spectrum on many dimension situations in the form of waterfall chart and fluorescent fingerprint, recording and replaying for a sig- nal spectrum. The experimental results show that the new system for spectrum monitoring works well, and has value of popularization and application.
