چکیده
|
To present focused isar imaging results in the homogenous range and cross-range domain,an integrated scheme is proposed to estimate both the targets equivalent rotational velocity (rv) and rotational center (rc). the rv estimation is improved by radial projection combined with keystone processing,and then the rc is estimated through image entropy minimization. finally,delicate imaging results may be obtained for wide-angle scenarios. experiment results are provided to demonstrate the effectiveness of the proposed method. © 2016 wei zhou et al.
