基于InSAR的沉降测量角反射器的制作与安装——以南票煤矿开采沉陷区为例

Fabrication and Installation of InSAR Based Settlement Measuring Corner Reflector:Taking Nanpiao Coal Mine Subsidence Area as an Example

合成孔径雷达(SAR)卫星具有全天候、全天时的观测能力,并对地表有一定的穿透能力,它在灾害监测、环境监测、资源勘察和军事应用等方面具有重要的作用,受到各国的普遍重视,目前已成为空间对地观测发展的热点。角反射器作为定标系统中的标准参考目标,其雷达截面积的精度和稳定度在很大程度上决定了定标测试的精度,因此,建立高精度的定标系统就需要研制高精度、高稳定度的角反射器。本文通过南票煤矿开采沉陷区基于InSAR的沉降测量工作,研究了角反射器的制作与安装方法。

Synthetic aperture radar （SAR） satellite has all- weather, all -clay observation ability, and has certain ability to penetrate to the surface, it＇s in disaster monitoring, environmental monitoring, resource survey and military applications play an important role, is paid great attention to by all countries, has now become the hot destination of space development of earth observation. Because of comer reflector as reference standard for calibration system of target, the precision of the radar cross - section and stability to a great extent, determines the scaling test precision, thus establish a high precision calibration system requires high precision, high stability of corner reflector. In this article, through the south vote＇ s coal mining subsidence area based on the settlement of InSAR measurements, production and installation of comer reflector is studied.
