The Australian NWC (North West Cape) signal transmitter is known to strongly interfere with the topside ionosphere. We analyze 456 conjunctions between Swarm A, B and NWC, in addition to 58 conjunctions between NorSat‐1 and NWC. The in‐situ measurements provided by these satellites include the 16 Hz Swarm Advanced Plasma Density data set, and the novel 1,000 Hz plasma density measurements from the m‐NLP system aboard NorSat‐1. We subject the data to a detailed PSD analysis and subsequent superposed epoch analysis. This allows us to present comprehensive statistics of the NWC‐induced plasma fluctuations, both their scale‐dependency, and their climatology. The result should be seen in the context of VLF signal transmitter‐induced plasma density fluctuations, where we find counter‐evidence for the existence of turbulent structuring induced by the NWC transmitter.

NWC甚低频信号发射器引起的电离层等离子体波动

众所周知，澳大利亚NWC（西北开普省）信号发射器会强烈干扰顶面电离层。我们分析了群A，B和NWC之间的456个连词，以及NorSat-1和NWC之间的58个连词。这些卫星提供的现场测量包括16 Hz Swarm高级等离子体密度数据集，以及NorSat-1上m-NLP系统提供的新颖的1,000 Hz等离子体密度测量。我们对数据进行了详细的PSD分析和随后的叠加历元分析。这使我们能够提供NWC引起的血浆波动的全面统计数据，包括其尺度依赖性和气候。应在VLF信号发射器引起的血浆密度波动的背景下查看结果，
