论文摘要
低频无线电光谱仪（LFRS）是2018年12月推出的Chang'e-4 Lunar Lander上的科学有效载荷。LFRS在人类历史上首次对月球远方的低频无线电现象提供了原位测量。为了评估LFR的性能，使用LFR的原型模型进行了一系列地面实验。执行实验并不容易，因为从chang'e-4月lunar lander本身中的EMI \脚注{缩写：EMI，电磁干扰}，环境非常强烈。 EMI缓解措施后的结果表明，LFR的灵敏度可能为1E-18WM^2Hz^-1。
The Low-Frequency Radio Spectrometer (LFRS) is a scientific payload onboard the Chang'e-4 lunar lander launched in December 2018. The LFRS provides in-situ measurements of the low-frequency radio phenomena on the far-side of the Moon for the first time in human history. To evaluate the performance of the LFRS, a series of ground experiments are conducted using a prototype model of the LFRS. It is not easy to perform the experiments because the EMI \footnote{ Abbreviation: EMI, Electro Magnetic Interference} from the Chang'e-4 lunar lander itself and the environment is very intense. The results after EMI mitigation show that the sensitivity of the LFRS may be 1e-18Wm^2Hz^-1.
