The Solar and the Lunar RFI Test for the 40m Radio Telescope

In this paper, the noise temperatures of the Sun and the Moon are measured using the calibrations of the standard radio sources and the standard noise. Our conclusions are:(1) If the 40m antenna is pointed to the Sun with in the angle ≥2°, it will not interfere the DAS(Dada Acquisition Subsystem).(2) The lunar noise temperature for 40m telescope is 87.1K, that means, DAS can work normally even 40m antenna pointing to the moon exactly.
