In whichever jamming mode, the jamming effect of spaceborne SAR mainly lies on the similarity between jamming signal and spaceborne SAR echo, namely signal structure and character of similarity between the two. In this paper, an active jamming method for spaceborne SAR based on the scattering statistical characteristics (SSC) is proposed. The mathematical mode of clutter-like signal used for jamming spaceborne SAR is constructed, the scattering statistics characteristic similarity between spaceborne SAR echo and this jamming signal is analyzed and simulated. Results show that this method has a better interference effect under the same jamming signal ratio and a better application prospect.
