Abstract

A structural displacement estimation method is performed by a computer program executed in a computing device. The computer program may cause a processor of the computing device to perform an automatic initial correction step and a structure displacement monitoring step. The automatic initial correction may be performed by: collecting measurement values from each of a radar device and an accelerometer directly installed on a structure; automatically determining one optimal target in a plurality of target candidate groups including targets detected by the radar device; and automatically calculating final transform coefficients for transforming a displacement in the direction of the line of sight to the optimal target into a displacement in an actual vibration direction. The structural displacement monitoring can increase the accuracy of structural displacement measurement by calculating a final displacement by fusing, on the basis of an FIR filter, a radar-based displacement obtained by applying the final transform coefficients to phases extracted from radar measurement values for the optimal target and an acceleration-based displacement obtained by double-integrating measurement values collected from the accelerometer.
