Abstract：Research purposes:The interpretation and application of remote sensing images, including aerialphotos and satellite images, have become the indispensablemethod for railway engineering geological survey. This paper introduces the image characteristics of SAR sensors and imaging process, analyzes the SAR image applications in railway engineering geological survey and sums up the response characteristics of radar echo for the purpose of providing the scientific basis for selection of the data on band, polarization, angle of incidence and illumination direction etc.
Research conclusions:(1) The perfect results of lithologic identification and lineament features interpretation can be obtained by adopting SAR composite images for some geologic surveying andmapping. (2) It is proposed thatSAR data should bewidely applied in the railway engineering geological survey along with optical sensing images because of its unique advantages.
