地基雷达IBIS-S系统在微变形监测领域展现了巨大优势。本文介绍了IBIS-S系统的工作原理,同时论述了IBIS-S变形监测信号中静杂波相位分量的产生原因及去除方法。通过模拟形变监测实验,验证了IBIS-S变形监测信号受到静杂波的影响。实验结果表明,变形监测数据经过静杂波去除处理后相对误差明显变小,说明了静杂波去除处理的必要性。
Ground-based radar The IBIS-S system offers tremendous advantages in the field of micro-deformation monitoring. This paper introduces the working principle of IBIS-S system and discusses the causes and removal methods of static clutter phase components in IBIS-S deformation monitoring signals. Through the simulation deformation monitoring experiment, it is verified that the IBIS-S deformation monitoring signal is affected by the static clutter. The experimental results show that the relative error of the deformation monitoring data after the static clutter removal is obviously smaller, which illustrates the necessity of static clutter removal.
