Inthis paper, we propose to utilize the adaptive timefrequencyanalysis technique to suppress the transientinterference. It firstly parameterizes the radar signal, thenthe transient interference as well as the ocean/groundclutter and target signal can be separated in parameterspace, thereby implementing the interference suppression.No data interpolation is involved in this technique, henceit may provide better suppression performance whenrelatively long transient interference appears or shortcoherent integration time (CIT) is used. 收起
