Abstract :
In this paper, the signal properties for the translational invariant case of bistatic synthetic aperture radar (SAR) based on the squint mode are deduced. Bistatic range history, point target response in time and frequency domains, Doppler properties and resolutions are presented in terms of the platform coordinates and the squint angles. The results are valid for large aperture and large squint angles. The accuracy of quadratic approximation in bistatic SAR is also discussed.
