提出了通过加速度传感器来建立雷达天线阵面工作变形的实时测量系统，该系统避免了激光测量法中基准不稳定影响测试精度，和采用位移传感器直接测量无法消除基础位移等问题，并通过试验测试验证了频域数字积分的精度，解决了测试数据通过高频汇流环进行数据实时传输等问题，为实时把握天线阵面变形对电性能的影响和改进天线阵面的结构设计提供了科学依据。

This paper proposes a real-time measuring system of operational deformation of radar antenna based on accelerometer. The system doesnt demand a stable benchmark which is necessary for laser measurement, and requires eliminating the foundation displacement. The precision of frequency integration is validated via test and the problem of data real-time transformation via a microwave transmission circuits is solved. It is the first time for radar structure development to get influence of antenna deformation on its operation performance.
