南极冰盖是地球上最大的大陆冰，其物质收支和稳定性对全球气候变化和海平面上升有着重要影响。冰雷达是冰川学家研究南极冰盖次表层性质的主要手段。近50年来，冰雷达已被广泛应用于冰盖厚度的测量，并取得了很好的效果。内部结构和冰下形态。这些参数是计算冰体积和质量平衡以及重建过去积雪和融化速率、冰动力学和沉积过程的基础。现在，RES覆盖了南极洲大部分地区，为了解冰盖与全球系统之间的相互作用提供了重要的信息。介绍了冰雷达及其技术发展，重点综述了冰雷达在南极冰盖厚度和冰下地形、内反射层、冰下湖泊和水系、冰下基岩粗糙度和晶向组构（COF）调查研究中的进展，并对冰雷达在南极冰盖调查研究中的应用前景和我国的现状进行了展望。
The Antarctic ice sheet is the largest continental ice on the earth and its mass budget and stability has an important influence on global climate change and sea level rise.Ice radar,or radio-echo sounding(RES),constitutes the principal means by which glaciologists investigate the subsurface properties of the Antarctic ice sheet.In the past fifty years,ice radar has been widely applied to measure ice sheet thickness,internal structure and subglacial morphology.These parameters are fundamental for the calculation of ice volume and mass balance as well as the reconstruction of past snow accumulation and melting rates,ice dynamics and deposition process.Now,RES has covered most regions in Antarctica and provided significant understanding of the interactions between ice sheet and global system.We briefly introduced ice radar and its technical development firstly and then mainly reviewed the progress of ice radar in investigating and researching Antarctic ice sheet thickness and subglacial topography,internal reflecting horizons,subglacial lakes and water systems,subglacial bedrock roughness and crystal orientation fabrics(COF).Finally,the prospect of ice radar in investigating and researching Antarctic ice sheet in the future and our present situation was proposed.
