In this letter, the fourth-order extended exact transfer EETF4) is adapted for spaceborne bistatic synthetic aperture radar (SAR) processing. The problems with high squint and large bistatic Doppler centroid variations are analyzed, and it is shown that if both transmitter and receiver are highly squinted in the same direction, then it may be demanding to achieve perfect quality of the point targets. It is shown that if both transmitter and receiver have high squint in opposite directions with small Doppler centroid variations, then the SAR image can be processed very precisely.
