摘要

近年来,全球导航卫星系统的应用领域越来越广泛。它提供使用个人位置信息的服务。但是,对某些人来说,这是不受欢迎的服务。因此,这些人开始使用个人隐私设备。需要对PPDs的影响和有效的对策进行研究。本文分析了PPD干扰机对抗干扰技术的影响。采用降秩方法消除扫频干扰的影响。我们还分析了降阶方法的性能。

The improved spatial nuller with frequency swept jammer
Recent years, the GNSS has a diverse and wide application field. It provides the services that using the personal location information. But, for the some people, it is undesirable service. Therefore, these people start using the Personal Privacy Devices. A study about the impact of PPDs and effective countermeasure to PPDs are required. In this paper, we analyze the effect on the anti-jamming technique by the PPD jammer. And we show the effect of frequency swept jammer is removed by applying reduced-rank approach. We also analyzed the performance of reduced-rank approach.
