The slanting flight mode bistatic SAR system has a flexible configuration and broad application prospects.However

because of the transceiver platform's movement in the range direction

the equation of instantaneous slant range gets very complex

and motion compensation also becomes rather difficult.Through an analysis of squint flight mode geometries

the thesis expounds the keystone of motion compensation in the range domain on slant flight mode

and presents two methods of motion compensation-the taylor approximation method and model approximation method.Then through analyzing the echo which has compensated the deviation in the range domain

the bistatic SAR Algorithm with range walk correction in time domain is conducted completely.Simulation results show that the motion compensation model approximation method is superior to the first-order taylor approximation method

and is equal to the second-order taylor approximation method

as well as verify the effectiveness of the method of slanting flight mode bistatic SAR imaging.
