摘要
针对常规扫描式合成孔径雷达(scanSAR)图像拼接效果较差,存在二维拼缝的问题,提出一种相控阵scanSAR工作模式,该模式利用相控阵天线波束具有快速切换的特点,使波束在各子测绘带之间进行脉冲级切换,再结合提出的成像方法,可以获得无缝拼接的scanSAR宽测绘带图像,克服了常规scanSAR的缺点。理论分析和仿真验证都表明了所述方法的正确性和有效性。
Aiming at the problem that the mosaic effect is bad and 2-D mosaic-sew exists to the gen- eral scanSAR image,this paper puts forward a phased array scanSAR operating mode,which uses phased array antenna beam has characteristics of rapid switch to make the beam perform pulse switch among sub-swathes, then combining with the imaging method proposed in this paper, the scanSAR wide swath image without mosaic-sew can be obtained which overcomes the shortcoming of conventional scanSAR. The theoretical analysis and simulation validation indicate that the meth- od is correct and effective.
