Abstract:

In the traditional inverse synthetic aperture radar (ISAR) imaging, the range instantaneous Doppler (RID) algorithm based on Clean technique has been widely used to extract the scattering center. Comparing with the traditional ISAR, the polarimetric ISAR (Pol ISAR) can supply more information about the target. An ISAR imaging method via RID algorithm combined with polarimetric technique is proposed. With this method, the bright scatterers are extracted accurately and the data volume decreases greatly, the fusion of polarimetric channel information performs well. Meanwhile, the effect of noise is weakened farther, thus avoiding false point targets. By simulated data, the effectiveness of the propose method is validated.
