| 摘 要： | 针对机载SAR运动补偿的需求,以DSP为处理器设计了一套SINS/GPS组合导航系统。使用强跟踪卡尔曼滤波算法估计系统误差,利用闭环校正法进行修正,实现了SINS/GPS的数据融合。通过Matlab仿真和跑车实验验证了系统设计的可行性和有效性。该系统具有低成本、实时性和同步于SAR雷达PRF信号的优点。

| Abstract: | Design a SINS/GPS integrated navigation system for airborne SAR motion compensation based on DSP processor.Strong tracking Kalman filter was used to estimate the system,and fuse the SINS and GPS data with closed loop emendation.The Matlab simulation and sports car experimentation prove the validity and effectivity of this design.This system based on DSP has the advantage of low-cost,real-time and synchronizes with the PRF signal of SAR. |
