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 theMoon for the first time in human history.To evaluate the performance of the LFRS,a series of ground experiments are conducted using an engineering model of the LFRS.It is not easy to perform the experiments because the Electro Magnetic Interference(EMI)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 10^(−18)W m^(−2)Hz^(−1).
