The improvement of displacement measurement algorithms by Step Frequency Radar

Step Frequency Radar and interferometric technique can be combined to measure the displacement of a bridge. Based on the reason of ambiguous high resolution range profiles of stepped frequency radar, the algorithms to achieve unambiguous high resolution range profiles is analyzed. And a new algorithms to achieve real one-dimensional profiles is proposed. Secondly, because of the ambiguous displacement measured by interferometric technology, the solution which can be called conjugate phase multiplication is proposed. Finally, the validity of these methods are verified by simulation.
