New moving target monitoring mode with Hybrid-TOPS of spaceborne SAR

  • 摘要: 针对传统星载合成孔径雷达(SAR)模式下运动目标测速范围有限、精度低等问题,本文提出了一种基于Hybrid-TOPS的星载SAR运动目标监视新模式。首先,利用混合度因子对星载SAR成像模式进行定量化的描述。在此基础上,通过TOPS模式与逆TOPS模式的组合提出一种运动目标监视新模式,该模式不仅能实现对同一区域的多次观测,且具有方位向连续观测的能力。然后,利用新模式所获取的不同方位向观测角度下的SAR序贯图像,再结合图像配准和基于新模式的运动目标参数反演即完成目标方位向速度信息的精确提取。最后,仿真验证了新模式的有效性与运动信息提取的精确性。
