Abstract :
For high quality synthetic aperture radar (SAR) processing, Doppler parameter estimation is an essential procedure. In this paper, the azimuth data of bistatic forward-looking SAR are modeled as cubic polynomial phase signals, and the CPF-Radon transform is used to estimate the high order Doppler parameter. Simulation results validate the effectiveness of this method.
