| 摘 要： | 该文在分析高分辨率机载SAR对运动补偿系统指标要求的基础上提出了一套基于SINS/GPS组合的高精度运动补偿方案。该方案采用两套独立的捷联导航算法,既具有一般SINS/GPS组合的优点,又有效地隔离了对高分辨率SAR成像有严重影响的GPS高频噪声。仿真实验和半物理防真实验结果证明了该方案的可行性。

| Abstract: | Abstract Based on analyzing the restriction of high-resolution SAR to motion errors, a high-accuracy integrated SINS/GPS system for SAR compensation is proposed. By the adoption of two individual strapdown navigating algorithms, this system not only can fully inherit the advantage of SINS/GPS system, but also can isolate the high frequency GPS noise which has serious impaction on high resolution SAR imaging. The feasibility is proved by computer simulations and semi-physical simulations. |
