| Abstract: | A method for inverse synthetic aperture radar(ISAR) cross range-scaling is presented to be adapted to engineering application.Based on smoothness,subsection and fitted of phase position data,the estimation of the rotation angular velocity is completed,and the effect of scatter distributing is analyzed.The processing of simulation and real data show that the proposed method is effective and applicable.Finally,some rules to improve the precision of scaling are put forward on the basis of engineering experience. |
