Abstract (EN): The research developed in this article, aimed to the structural monitoring of a telecommunication pole with a recently developed monitoring system, using radar IBIS-FS. This system comprises a radar which uses as working principle the interferometry technique. The main purpose of this work is to validate the results obtained from the radar and its comparison with numerical model of the corresponding telecommunication pole. The present work describes a dynamic analysis of the structure under ambient vibration conditions, with the main goal of obtaining the natural frequencies and structural mode shapes. As a complement was still made a numerical structural computational model with the necessarily data for the geometric and mechanical characterization of the structure. With this model it was possible to carry out a modal analysis, in order to obtain a comparison of the frequencies of the vibration modes between the numerical model and the analysis performed using the radar IBIS-FS.
