On Measuring Range Expanding of Micro Deformation Measurement of Buildings Based on Electromagnetic Wave

为了在保持测量精度不变的情况下提高基于电磁波测量建筑物变形方法的测量量程,提出了对中频信号N分频从而将测量范围提高N倍的方法.经过仿真,该方法能够正确计算出测量过程中目标形变量超出测量量程的情况,解决了测量精度与量程之间的矛盾,在实际应用中具有重要的价值.

In order to expand measuring range of micro deformation,N times demultiplication of frequency at medium frequency has been presented in this paper and measuring range is N times expended.Simulation results show that the number of cyclic skipping can be detected with this method and micro deformation of buildings can be measured precisely.This method solves detection fuzzy problem of micro deformation measurement of buildings and it is very important in practical use.
