本文介绍了一种用于地表变化监测的被动合成孔径雷达的概念验证方法和结果。双基地拓扑结构包括导航卫星（如全球定位系统、全球导航卫星系统（GLONASS）、伽利略或北斗）作为机会发射器和地面固定接收器。地表监测将通过连贯的变化检测来提供。介绍了为验证该系统的概念而搭建的实验试验台，并给出了相应的实验方案。给出了变化检测的初步信号处理算法。将实验测量的变化与理论预测进行了比较，并对所得结果进行了讨论。
This paper presents proof-of-concept methods and results on a passive synthetic aperture radar for surface change monitoring. The bistatic topology comprises navigation satellites (such as Global Positioning System, GLObal Navigation Satellite System (GLONASS), Galileo, or Beidou) as transmitters of opportunity and a fixed receiver on the ground. Surface monitoring is to be provided through coherent change detection. An experimental test bed built to confirm the concept of the system is described, and the appropriate experimental program is presented. Preliminary signal processing algorithms for change detection are derived. Experimentally measured changes are compared to the theoretical predictions, and the obtained results are discussed.
