Efficient Narrowband RFI Mitigation Algorithms for SAR Systems With Reweighted Tensor Structures

Radio-frequency systems, such as TV and cellular networks, severely interfere with synthetic aperture radar (SAR) systems. Narrowband radio-frequency interference (RFI) has a special low-rank property in the received signal matrix, because it performs like a sinusoid with nearly invariant frequency...
