摘要
论述具有三维测绘能力的干涉式合成孔径雷达（ＩｎＳＡＲ）测量技术。在ＩｎＳＡＲ中，除了形成普通的二维ＳＡＲ图像之外，还利用同一地物目标的两幅ＳＡＲ图像的干涉相位来提取该地物的高度信息。详细阐述ＩｎＳＡＲ的基本原理，分析其测量精度极限性能和某些设计约束，并概要介绍若干试验结果。
In this paper, the interferometric synthetic aperture radar (InSAR), which has three dimensional topographic mapping capability, is described in detail. The basic principles, pixel height measurement accuracy, performance limits and some design restrict conditions, and some experiment result summary for two antenna InSAR and repeat pass InSAR are explained deeply.
