【 摘 要 】

The basic theoretical principles and key techniques of the IBIS-S system, which is a micro-deformation monitoring system based on the techniques of GB-InSAR, are introduced. The accuracy of IBIS-S is much higher than that of traditional deformation monitoring devices, so it is necessary to test the accuracy and reliability of the system. Some comparison experiments are designed for testing the parameters provided by the manufacturer, and these tests verify the accuracy and resolution of IBIS-S. A Leica TCRP 1201 total station (with an accuracy of 1mm + 1ppm) and a stepping motor (with an accuracy of 0.001mm) are used for testing the monitoring accuracy of IBIS-S. The results from different tests show that the monitoring data of IBIS-S is very accurate and higher than the traditional total station. The results also indicate that IBIS-S can be applied in the micro-deformation projects of high-rise buildings, bridges and some other objects with a high accuracy.
