Vibration imaging for the characterization of extended, non-cooperative targets

The imaging vibrometer development will be based on a representative Directed Energy (DE) aperture assumed to be 30 cm. This effort will provide both DE and Combat IDentification (CID), modes for relative short range DE operations, and an ISR Combat IDentification (CID) mode for operation at extended range. A combination of analytic derivations and wave optics simulations will be used to define a realizable conceptual system design, and characterize its performance over this wide imaging space. Both representative target and atmospheric phenomenologies relevant to vibration imaging will be analyzed. Simulated will provide detailed descriptions of the changing speckle fields and their impacts on the vibration measurements. The results of the simulation will be used to refine the initial Conceptual Design and provide an initial specification for a scaled system to be implemented in Phase II. This research will enable deployment of vibration imager for both signature and phenomenology experiments as well as future operational applications.
