| 摘要: |
| 弹载合成孔径雷达（Synthetic Aperture Radar,SAR）成像需依托弹道参数完成斜距图像向地距图像的几何校正，在俯冲大前斜SAR成像模式下的几何校正性能对弹道参数的精度非常敏感。针对弹载俯冲大前斜视SAR成像模式下成像斜距图为距离多普勒类型图像的几何校正算法，从理论上分析了多维弹道参数误差带来的几何校正畸变量，通过仿真验证了算法及畸变量分析的有效性。该研究对雷达导引头的系统设计、目标识别技术需求等提供了理论依据，具有重要的工程应用价值。 |

| Abstract: |
| Missile-borne synthetic aperture radar(SAR) imaging should perform geometric correction which depends on ballistic parameters.The geometric correction performance is very sensitive to ballistic parameters on diving high-squint SAR model.The influence of missile multidimensional parameters is analyzed theoretically for the geometric correction algorithm of diving high-squint SAR model.The simulation results demonstrate the validity of this algorithm.This study in this paper provides a theoretical basis for missile seeker system design and target identification requirements.It has important engineering application value. |
| Key words: synthetic aperture radar(SAR) diving maneuver high-squint SAR geometric correction ballistic parameter |
