Abstract
This paper presents a multiple input multiple output (MIMO) wireless radar sensor network capable of measuring lower-frequency vibration and static deflection in bridges. An integrated simulation model that combines a multi degree-of-freedom structural model with a realistic model of the radar sensor network is introduced and used to characterize and predict the network’s functionality in different measurement conditions. In addition, a series of laboratory experiments have been performed for comparison with the simulation model. Finally, challenges associated with achieving accurate measurements from the radar network in a range of testing environments are discussed.
