摘要
地下开采导致的地表形变失相干是InSAR技术在矿区开采沉陷监测中面临的主要问题。本文分析了In-SAR技术用于矿区开采形变监测的适用性和最大可探测形变梯度问题,并以陕西彬县彬长矿区为研究对象,采用PALSAR数据进行矿区开采沉陷探测实验研究,研究结果表明:PALSAR数据因其波长较长的特点,具有相对较大的监测梯度,在一定程度上能够克服矿区形变量超出最大监测梯度所造成的失相干现象。
Decoherence phenomenon caused by mining subsidence is the main question in mining subsidence monitoring. This pa- per taking Binchang mine area in Shaanxi as a study region, analyzed the applicability and the maximum detectable deformation gradi- ent about the InSAR technique used in mining deformation monitoring. The research resuhs showed that： because of longer wavelength characteristics, PALSAR data has relatively larger monitoring gradient, which would help overcome decoherence phenomenon caused by the deformation beyond maximum monitoring gradient.
