摘要翻译:
我们描述了一种利用单颗卫星识别卫星干扰源的方法。该技术依赖于这样一个事实,即在下行链路站测量的载波信号强度由于许多因素而随时间变化,我们使用量子启发算法来计算信号的“特征”,该特征捕捉上行链路天线特征的部分变化模式。我们定义了一个距离测度来数值量化两个信号之间的相似程度,并通过计算干扰载波信号与同一卫星同时中继的已知载波信号之间的距离来识别干扰源天线,如果已知载波从中继的话。作为概念的证明,我们使用一个应用于测量载波数据的简单统计模型来评估该技术的性能。

英文摘要:
  We describe a method for identifying the source of a satellite interferer using a single satellite. The technique relies on the fact that the strength of a carrier signal measured at the downlink station varies with time due to a number of factors, and we use a quantum-inspired algorithm to compute a 'signature' for a signal, which captures part of the pattern of variation that is characteristic of the uplink antenna. We define a distance measure to numerically quantify the degree of similarity between two signatures, and by computing the distances between the signature for an interfering carrier and the signatures of the known carriers being relayed by the same satellite at the same time, we can identify the antenna that the interferer originated from, if a known carrier is being relayed from it. As a proof of concept we evaluate the performance of the technique using a simple statistical model applied to measured carrier data.
