摘　　要：为了提高地基雷达系统的监测精度,提出一种新的高精度的地基合成孔径雷达干涉GBSAR(Ground Based SAR)监测技术。融合了GBSAR关键技术以及数据处理理论,对影响测量精度的误差项进行了分析研究并从3个方面(雷达系统、数据获取、数据处理)具体给出了相应的精度提高措施。基于变形监测系统(IBIS-S)对GBSAR理论研究进行实验验证。实验表明GBSAR技术对于目标体的监测精度较高。最终得到GBSAR技术产生的误差的途径主要源自数据采集的过程。In order to enhance the accuracy of the ground radar system recognition, it presented a new monitoring technology of ground based SAR （GBSAR） which has a higher precision. It fuses the theories of GBSAR key technology and data processing. And it analyzed the errors which affect measurement accuracy of GBSAR are classified in terms of three parts：radar system, data acquiring and data processing steps. It validated GBSAR by experiment based on IBIS-S system. The experimental results showed that GBSAR has high precision for aim subject. These errors of GBSAR mostly originate from data-collection process.
