| 摘 要： | 运动补偿系统设计是机载SAR实现高分辨率的一项关键技术,DGPS/IMU组合导航系统已成为当前高分辨率机载SAR基于传感器的运动补偿技术的发展趋势之一.将一种双向卡尔曼平滑滤波算法应用于DGPS/IMU组合导航系统中,实验表明与多传感器组合导航系统数据处理中最常用的算法工具--卡尔曼滤波器相比,该算法可以为机载SAR提供更高精度的运动补偿信息.

| Abstract: | In the Synthetic Aperture Radar(SAR) Imaging,generation of fine resolution imagery requires high accuracy Motion Compensation.DGPS/IMU Integrated Navigation System is adopted in many leading SAR systems for the use of Motion Compensation.An application of forward-backward filter arithmetic is described in DGPS/IMU Integrated Navigation System.The precision is enhanced remarkably than Kalman filter which has been used widely in mulit-senter integrated navigation system.Higher motion compensation information ... |
