| 摘 要： | 针对弹载合成孔径雷达(SAR)成像存在运动参数抖动的问题,分析了不规则运动造成图像几何失真的机理,提出了一种基于多项式逼近的弹载SAR线性调频(LFM)信号前斜视成像几何形变校正方法。挂飞试验证明,该方法能从雷达回波数据中准确消除几何形变,提高成像质量。 |
| 关 键 词： | 合成孔径雷达 运动补偿 几何形变校正 雷达成像 |

| Abstract: | In order to solve the problem of motion parameters vibration,which causes the image geometric distortion,the mechanism is studied and a method of geometric distortion correction based on polynomial approximation for LFM SAR is proposed.Experiments show that the new method can provide accurate parameters for missile-borne SAR imaging and useful to improving the image quality. |
