Time-frequency analysis of RFI data and interference suppression using match pursuit algorithm
In this paper, we analyze the characteristics of the radio frequency interference (RFI) data in the time-frequency domain. A matching pursuit (MP) method is proposed for RFI suppression in ultra-wideband synthetic aperture radar (UWB-SAR) system. The algorithm decomposes the SAR echo over a modified Gabor dictionary to remove the significant RFI. The performance for the algorithm is investigated by using the raw data.
