  • Airborne squint mode SAR has the advantages of better flexibility and larger field in applications than the classic sidelooking mode SAR. But the imaging processing of squint mode SAR is a strict two-dimensional phenomenon. This paper compares the 2-D FFT method, fast polynomial transform(FPT) method and two 1-D FFT method for the imaging processing of squint mode SAR.
