Abstract

A novel mode of space-aero bistatic SAR, in which the spaceborne transmitter is side-look and the airborne receiver is forward-look, is studied. The characteristics of the traditional forward-look SAR is discussed to compare with the special space-aero bistatic forward-look SAR. Because the range direction of the transmitter is the azimuth direction of the receiver in this mode, the´ forward-look SAR does not like the traditional forward-look SAR, it can acquire high azimuth resolution by using the range compression. Through the analysis of Doppler characteristic and echo signal model, the equidistance line of this mode is quite similar to that of squint SAR is pointed out, which enables the transplantation of existed well-rounded imaging algorithm of squint SAR to this mode. The imaging algorithm and simulation experiment are presented
