| 摘 要： | 在测量雷达空间标校目标时，采用固定觇牌作为观测标志。为获得标志的绝对位置和标志之间较高的相对精度。采用GPS-C级进行平面控制测量，采用二等水准进行高程控制测量，采用高精度全站仪极坐标法和边角前方交会法进行标志的坐标测量，采用对向测距三角高程联合二等水准进行标志的高程测量。精度分析和实际应用表明；观测成果是可靠的，采用几种精密测量方法联合进行，可以满足观测标志的高精度要求。

| Abstract: | Fixed target is adopted as observation mark in marking targets of surveying radar.For acquiring absolute position of the mark and high relative accuracy among marks,horizontal control survey is used with GPS C-order and vertical control survey is used with second-class leveling.Polar coordinate method of high precision total station and forward intersection method of triangulation is adopted to measure coordinates.Subtending distance measurement trigonometric leveling uniting second-class leveling is adopted to measure height.The precision analysis and practical application indicate that all the results are reliable and united several precision surveying methods can satisfy high accuracy. |
