A Keystone Transform for Dual-Channel SAR Moving-Target Imaging

摘要：

The paper proposes a moving-target imaging method for dual-channel DPCA SAR which can remove linear and quadric range migration simultaneously by introducing a phase compensating component during Keystone. CZT-IFFT is exploited to improve computation efficiency. Moreover, the method exploits chirp parameters estimated by MDCFT joint slope parameters estimated by channel phase difference filtered in fractional Fourier domain to calculate velocity, acceleration and azimuth position of moving-target. Simulation results prove that the method is correct.
