| 英文摘要 | This paper deals with the imaging problem of one-stationary bistatic sar (bisar) with large bistatic angle. an improved nonlinear chirp scaling (nlcs) algorithm is proposed for this bisar. the main work here includes three aspects. first, a range chirp scaling function for correcting the differential range cell migration correction is derived. then, the azimuth perturbation is generated by local fit method, which makes the nlcs algorithm suitable for the large bistatic angle case. furthermore, the negative effects introduced by the perturbation (including phase error and locality error) are discussed, and some compensation methods are proposed to enhance the capability of the algorithm. the simulating results exhibited at the end of this paper validate the correctness of the analysis and the feasibility of the algorithm. |
