北极黄河站科学考察（2022年）成像式宇宙噪声接收机观测数据

接收机工作频率为38.235 MHz，天线阵合成波束为7×7的方阵，天线阵一边指向不变磁纬的正北方向。相对稳定的38.235 MHz宇宙噪声穿过电离层时，由于波粒相互作用而发生衰减，衰减程度与路径上电子的浓度及电子与其它粒子的碰撞频率有关。

The receiver operates at a frequency of 38.235 MHz, with its antenna array generating a 7×7 square synthetic beam. One side of the antenna array points toward the true north of the invariant magnetic latitude. When the relatively stable 38.235 MHz cosmic noise passes through the ionosphere, it undergoes attenuation due to wave-particle interactions, and the attenuation level is related to the electron concentration along the propagation path and the collision frequency between electrons and other particles.

This dataset consists of observation data collected by the imaging cosmic noise receiver at the Chinese Arctic Yellow River Station in 2022. Analyzing ionospheric parameter variations using such observational data is of great significance for understanding changes in the polar space environment.
