CLEAN Technique for Polarimetric ISAR

[摘要] Inverse synthetic aperture radar (ISAR) images areoften used for classifying and recognising targets. To reduce theamount of data processed by the classifier, scattering centresare extracted from the ISAR image and used for classifyingand recognising targets. This paper addresses the problemof estimating the position and the scattering vector of targetscattering centres from polarimetric ISAR images. The proposedtechnique is obtained by extending the CLEAN technique, whichwas introduced in radar imaging for extracting scattering centresfrom single-polarisation ISAR images. The effectiveness of theproposed algorithm, namely, the Polarimetric CLEAN (Pol-CLEAN) is tested on simulated and real data.
