Ground Experiments and Performance Evaluation of the Low-Frequency Radio Spectrometer Onboard the Lander of Chang'e-4 Mission [IMA]

http://arxiv.org/abs/2012.04347


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.
