摘　　要：分析了天线转台倾斜对三坐标雷达测高精度的影响,通过对测高误差进行量化分析,找准误差修正工作的重点和难点。经研究表明,测高误差主要是天线辐射波束仰角偏差引起,可通过对测高值的实时比对分析和对辐射波束仰角的实时调整,实现了测高误差修正。研究提出了针对天线转台倾斜引起的三坐标雷达测高误差的修正方案。The 3D（three dimensional）-radar altimetry error caused by antenna rotary table slope is analyzed. By means of quantification analysis, the key points and difficulties in revising the errors are found out. Research shows that the altimetry definition error is mainly caused by radar beam elevation an- gle deviation, which can be revised by real-time comparison analysis of altimetry definition value and the real-time adjustment of radar beam elevation angle. A revision proposal for the 3D-radar altimetry defini- tion error caused by the reason aforementioned is proposed.
