| Abstract: | To obtain bistatic space-borne SAR wide swath images,a method is proposed based on multiple elevation receivers,which combines digital beamforming technology and the bistatic SAR imaging algorithm.The implement steps of it bases on the bistatic SAR squint mode are studied.Theory analysis and computer simulation prove the validity of the method. |
| Keywords: | bistatic SAR digital beamforming nonlinear chirp scaling algorithm wide swath |
