This paper addresses the wide range of mechanisms through which out‐of‐band interference can disrupt the functioning of GNSS receivers. These mechanisms include saturation and desensitization of front‐end low noise amplifiers, mixers and other circuitry; reciprocal mixing effects that arise from the fact that receivers cannot generate a perfect tone to down‐convert the desired signals; intermodulation products; aliasing of out‐of‐band emissions that remain after filtering into the receiver's passband; and the reception of in‐band (to GNSS) emissions that are always present due to imperfections in the signal generation and filtering of the interfering system. These mechanisms are described in detail and mitigation approaches for each are discussed.

带外干扰对GNSS接收机的影响概述

本文探讨了多种机制，带外干扰可通过这些机制破坏GNSS接收器的功能。这些机制包括前端低噪声放大器，混频器和其他电路的饱和和去敏。接收器无法产生完美的音调来下变频所需信号的事实而产生的互惠混合效应；互调产物；混入接收机通带后仍残留的带外发射的混叠；以及由于干扰系统的信号生成和滤波不完善而总是存在的带内（至GNSS）发射。详细描述了这些机制，并讨论了每种机制的缓解方法。
