Research Interests: RFI measurement and mitigation: When the telescope site was ensured, how do we deal with RFI in telescope constructing stage and telescope constructed stage? Maybe, we should determine interference level limits of the feed aperture for telescope firstly, and then care about spectrum management, interference measurement, electromagnetic wave propagation, emission evaluation and shielded solutions.
