简析两种不同数据采集方式对卫星干扰源定位性能的影响

Analysis of the Infl uence of Two Different Data Acquisition Methods on the Positioning Performance of Satellite Interference Sources

卫星干扰源定位中,1个目标信号和5个参考信号随机分布在一段带宽上面,如果采集卡能一次将6个信号同时采集,则为宽带采集模式;若6个信号需要分批次采集,则为窄带采集模式。文章分析了不同采集模式对干扰源定位精度的影响,并通过大量实验证实了宽带采集模式明显优于窄带采集模式。

In satellite interference source positioning,one target signal and five reference signals are randomly distributed over a bandwidth,If the acquisition card can simultaneously collect six signals at a time,then it is the broadband acquisition mode;If 6 signals need to be collected in batches,then it is the narrow band acquisition mode.This paper analyzes the influence of different collection modes on the positioning accuracy of interference sources.A large number of experiments have proved that the broadband acquisition mode is obviously superior to the narrow band acquisition mode.
