Impact Analysis of Motion Measurement Error on Array Antenna SAR Three Dimensional Imaging

  • 摘要: 阵列天线合成孔径雷达(SAR)可实现3维成像。为了提高成像质量,使用测量设备获取平台的运动信息以进行运动补偿,而测量误差会影响补偿及成像质量,需对其进行分析。该文首先建立了阵列天线SAR 3维成像模型和测量误差分析模型,接着分别从位置和姿态角两个方面分析了测量误差对相位误差的影响,并比较不同方向误差影响的大小,然后通过仿真分析了误差对成像指标的影响,并引入姿态误差基线比来量化姿态角误差的影响。最后得出高程向和横滚角测量误差影响最大的结论,给出了限定要求下测量误差的容忍值。该文的结论为测量设备的选取和设计以及成像和补偿方法的选择和分析提供了理论指导和参考。
