Imaging of Airborne bistatic SAR (synthetic aperture radar) which requires a two-dimensional space-variant correlation is like that of monostatic SAR.Different image algorithms use different approximation to handle the two-dimensional space-variant correlation.Approximation and relation of different algorithms are analyzed:algorithm with ignoring range-azimuth coupling
bistatic range-doppler algorithm
algorithm of straight applying stationary phase principle.The phase approximation of different algorithms is given in analytic.Finally
the simulation is given to validate analytic result.
