Abstract
In accordance with an embodiment, a method of monitoring a structural object includes performing a first set of radar measurements using a first millimeter-wave radar sensor to produce a first set of radar data, extracting a first interferometric phase from the first set of radar measurements, and determining a structural integrity of the structural object based on the extracted first interferometric phase.
