摘要:

低频无线电频谱仪(LFRS)是2018年12月发射的嫦娥四号月球着陆器上的科学有效载荷。LFRS在人类历史上首次提供了对月球远端低频无线电现象的现场测量。为了评估LFRS的性能,使用LFRS的原型模型进行了一系列的地面实验。由于嫦娥四号月球着陆器本身的电磁干扰\footnote{ Abbreviation: EMI, Electro Magnetic Interference}和环境非常强烈,因此进行实验并不容易。EMI缓解后的结果表明,LFRS的灵敏度可以达到1 e-18Wm^2Hz^-1。

英文摘要:

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.
