摘要

本文讨论了GPS的窄带/宽带混合潜在干扰，并描述了最近成功的技术演示结果，该技术证明了预相关时间滤波器解决窄带干扰的有效性。除了描述时间滤波器解决方案的工作原理及其在实验室测试中的干扰抑制性能外，本文还讨论了空军/五月花号预相关时间滤波器的潜在双重用途。预计商业GPS应用中的非故意干扰问题是窄带干扰的特征，因此可以通过所讨论的时间滤波器解决方案完全缓解。

Low-cost solution to narrowband GPS interference problem

This paper discusses the narrowband/wideband mix of potential interferences to GPS and describes the results of a recent successful technology demonstration which established the efficacy of a precorrelation temporal filter solution to narrowband interference. In addition to describing the theory of operation of the temporal filter solution and its interference suppression performance in laboratory tests, this paper discusses potential dual use applications of the Air Force/Mayflower precorrelation temporal filter. It is anticipated that the unintentional interference problem in commercial GPS applications is characteristic of narrowband interference, and therefore it can be fully mitigated by the temporal filter solution discussed.
