A New Range Migration Correction Algorithm and Its Simulation for SAR Altimeter

  • 摘要: 合成孔径雷达高度计可以获得比传统雷达高度计更高的测量精度,延迟校正是其中的核心技术。在雷达收发脉冲的间隔内,由于卫星运动,目标与雷达之间的距离变化会带来残余误差,这点在现有的延迟校正算法中都未考虑。该文研究了垂直速度和水平速度对延迟校正的影响,建立了合成孔径雷达高度计的延迟校正模型,提出了一个新的延迟校正算法,消除了卫星垂直速度和水平速度带来的残余误差。最后通过计算机仿真进行了验证,仿真结果表明,该文提出的算法可得到准确的校正结果。
