The present invention relates to a method for mechanically characterizing a structure (101) by means of a plurality of sensors in communication with a control unit (200), said method comprising: - a first positioning phase, wherein at least two sensors (120a, 120b) of said plurality of sensors are operationally connected to said structure (101) according to a first positioning scheme; - a first acquisition phase, wherein each sensor (120a, 120b) transmits to the control unit (200) at least one first signal representative of an acceleration of a portion (110) of said structure (101); - at least one further positioning phase, wherein at least two sensors (120a, 120c) of said plurality of sensors are operationally connected to said structure (101) according to at least one further positioning scheme; - at least one further acquisition phase, wherein each sensor (120a, 120b) transmits to the control unit (200) at least one further signal representative of a further acceleration of a further portion (110) of said structure (101); - an aggregation phase, wherein said control unit (200) aggregates a first set of modal parameters and at least one further set of modal parameters in order to obtain a single set of modal parameters mechanically characterizing the structure (101), wherein said control unit (200) determines the first set of modal parameters based on said at least one first signal and determines the further set of modal parameters based on said at least one further signal, and wherein said first positioning scheme and further positioning scheme comprise at least one common acquisition position of said sensors (120a).
