摘要
提出了一种导航卫星导航信号频谱自动化监测和判读软件设计和实现方案,该软件利用控制计算机通过通信端口控制频谱分析仪,进行分时设置各频点导航信号详细频谱参数。对频谱分析仪的显示屏幕进行屏幕拷贝、计算机机界面显示和自动保存,通过采集频谱分析仪的频谱数据,进行数据处理,得到每个频点导航信号在指定带宽内的通带功率,与预定的门限比较,超出门限,则判定异常,通过音箱,立刻发出报警声音,提醒相关人员进行及时处理。
A scheme of design and implementation of automatic monitoring and justifying software of navigation signal spectrum for satel lite is proposed. The software utilize the computer to control the spectrum analyzer and the detail parameters of the spectrum analyzer is sel through time divided mode. The display of the spectrum analyzer screen is hardcopy and saved automatically. After the spectrum data is sam pling and is processed, the band power of the every special navigation signal is obtained. The band power is compared with the setting thresh old value, if the band power exceeds the threshold value, the alarm signal is starting in order to remind the test engineer to deal with the problem in time.
