Abstract The polarization scattering matrix characteristic of the active decoys produced by the single polarized repeater is analysed under the background of the anti-jamming of the instantaneous polarimetric radar. It is shown that the characteristics of active decoys measured by the interleaved-pulse polarization agile radar and the instantaneous polarimetric radar are different, though the active decoys is produced by the same jamming mode. Further more, considering the scattering matrix may not be able to be measured accurately in the jamming situation, a preprocessing method in target reorganization based on the inadequate polarization characteristics is produced, employing which the three series of scattering matrix of target can be obtained which can be used as the robust features in target recognition.
