| Abstract: | Microwave remote sensing has great potential application in geological mapping for its ability to partly pass through shallow cover. The tone of radar image depends on the backward reflection index which is affected by many factors. To testify the penetrability of radar signal and simplify question, especially to get rid of the affection of vegetation at the same time, the study area was chosen in desert environment. There are four kinds of overlay covers including sand, loess, alkaline land and snow in the study area. Basing on the analysis of the property of different covering media and radar data parameters, we build information composition model of radar image in four different media covering area, which provide technique support for further microwave remote sensing information extraction and regional geological mapping. |
