Abstract

Abstract: The problem of inverse synthetic aperture radar (ISAR) imaging of a spinning target with high velocity is discussed. The feature of this kind of target is analyzed and the new scheme for the ISAR imaging is proposed. First the ISAR echo signal model of a spinning target with high velocity is presented. And then the ISAR imaging character of this kind of target is analyzed. According to this analysis, a method for ISAR imaging projection plane calculation is introduced. Computer simulations are presented which verify the proposed algorithms.

Key words: inverse synthetic aperture radar, spinning target with high velocity, projection plane, radar imaging
