Time-Varying RFI Suppression of Dechirping Radar Based on <italic>l</italic><sub>1</sub> Norm Filtering and RAM-Based Frequency Estimation

This paper presents a novel framework for suppressing time-varying radio frequency interference (TRFI) in wideband dechirping radar. The TRFI challenges the wideband radar because of 1) changing in wide spectra range; 2) dynamic nature and unpredictability; 3) significant noise power in limited band...
