Abstract :
Space-borne synthetic aperture radar is widely used in the military field. To counter space-borne SAR, it is necessary to estimate the parameters of space-borne SAR in real-time. After Receiving the signals of SAR, fractional Fourier transform is applied to both single pulse and pulse train, which can estimate the parameters in real-time. Theory analysis and Numerical simulation show this method has high accuracy.
