| S-SAR边坡雷达监测过程中由于边坡距离的不确定性，雷达监测数据普遍出现随机性、差异大等问题，致使雷达单一的预警参数无法准确地判断边坡稳定性。针对此类问题，以金中矿业采场边坡为工程背景，采用理论分析、现场实测等综合研究方法，分析了不同距离条件下S-SAR边坡雷达监测数据规律与控制对策。结果表明：S-SAR边坡雷达监测条件下，不同距离条件下S-SAR边坡雷达监测数据规律显现不同，监测距离越远，边坡雷达获取像素点面积越大，监测数据边坡变形量精度越低，导致无法准确分析监测数据，推断边坡稳定性。据此，以相同地质条件下的边坡基准，以不同的监测距离为分级指标，将采场监测范围内的边坡分为二级，给出了不同级别下的边坡雷达监测数据分析的控制对策，应用效果良好。 |

| During the S-SAR slope radar monitoring process， due to the uncertainty of slope distance， radar monitoring data generally exhibit issues such as randomness and large differences， resulting in the inability of a single radar warning parameter to accurately judge slope stability. In response to such problems，taking the slope of Jinzhong Mining as the engineering background， comprehensive research methods such as theoretical analysis and on-site measurement were adopted to analyze the patterns and methods of S-SAR slope radar monitoring data under different distance conditions. The results show that under the monitoring conditions of S-SAR slope radar， the patterns of S-SAR slope radar monitoring data show different under different distance conditions. The farther the monitoring distance， the larger the pixel area obtained by the slope radar， and the lower the accuracy of monitoring data slope deformation. This leads to the inability to accurately analyze monitoring data and better infer slope stability. Based on this， using the slope benchmark under the same geological conditions and different monitoring distances as grading indicators， the slopes within the monitoring range of the mining site are divided into three levels. Control strategies for analyzing radar monitoring data of slopes at different levels are provided， and the application effect is good. |
