| Abstract | We propose a multi-source radio frequency interference (RFI) mitigation method based on a reference antenna array to address the challenge of RFI from multiple directions in radio observation equipment. It introduces a sampling point correction technique using a multi-channel parallel cross-correlation computation method, enhancing the effectiveness of frequency domain adaptive RFI fast mitigation algorithms. The design implements an RFI component detection method based on cross-correlation coefficient thresholds to effectively reduce new interference frequency components introduced by the reference antenna array. Simulated RFI signals and baseband signals of pulsar J0332+5434 observed by the Nanshan 26 m Radio Telescope (NSRT) were used to test the algorithm proposed in this paper. Simulation results demonstrate that the simulated radio telescope signals after RFI mitigation closely match the original pulsar data in profile and phase, confirming the effectiveness of the proposed method. |
