TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)

The primary objective of this effort is to design and build a practical millimeter wave imaging system capable of effectively addressing a myriad of nondestructive inspection issues related to complex composites and structures during manufacturing and use.  The design of this imaging system will be founded on a long history and extensive experience by the proposing team facilitating and ensuring a successful outcome. The system is expected to be designed to:

i)operate in the frequency range of 30-40 GHz:

ii)have high-spatial and range resolutions in the few millimeter range rendering the system a 3D imager

iii)produce and render images in real-time,

iv)provide high system dynamic range for high detection sensitivity

v)small and portable for in-space applications,

vi)modular in design to accommodate large structures in terrestrial inspection applications while also suitable for in-space applications by personnel with varied technical skill-sets namely, technicians, engineers and astronauts.

The proposed work in this Phase II to develop, built and test a practical prototype imaging system builds on the Phase I design work.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The system proposed could be used to inspect: Thermal Protection Systems; High Temperature Reusable Surface Insulation; and Advanced Flexible Reusable Insulation. The proposed system would images these materials better and faster. Human Exploration Operations programs, e.g. crew transportation systems; ISS; Orion; deep space habitation; and Advanced Exploration Systems. The NASA/MSFC Meteoroid Environment Office (MEO) could use the system to determine location and depth of simulated micrometeoroids and orbital debris post impact testing. In-service, this capability could be used by people in space to determine the size and depth of debris and impact damage, allowing appropriate repairs. The camera could also be used to inspect multi-layer polymers, Nextel, ceramic fabrics etc such as those used in Whipple bumpers. While the camera cannot image through metal layers, such layers can act as reflectors and enhance imaging in materials above a metal layer. It could also be used to assess damage to the composite overwrap on pressure vessels. The system should be capable of imaging inside any dielectric material, including Kevlar fabrics, Kevlar/epoxy, fiberglass, and foams. The system could also be applied to inspection of more Earthbound applications within the Safety, Security and Mission Services/Construction & Environmental Compliance and Restoration programs. It could image composite, elastomer, polymeric, ceramic and civil materials for degradation.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The proposed systems non-ionizing energy can rapidly image hidden weapons. It can image, in 3D, features hidden inside walls. This includes substructure, pipes, wiring, joists, fasteners, etc through drywall, paneling, siding, plywood and other common materials. It could also be used to detect and determine the extent of damage such as mold, water ingress, termites/carpenter ant nests, etc. A related application would be civil engineering such as inspecting FRP repairs to bridge decks and FRP wraps around concrete columns. In the petrochemical industry, the system could be used to image blockages, build-ups, and damage in fiberglass pipes, tanks and pressure vessels. Microwave testing is being commercialized in the petrochemical industry for inspecting fiberglass vessels. The proposed imaging innovation would greatly expand these capabilities. When a material being tested for radar performance fails radar testing, it is currently difficult to discern the location in the structure that caused failure. We are developing a tool to localize anomalies that caused far field range test failures in radomes. While effective, the tool is raster scanned over the radome. The imaging system proposed here would be a much faster way to localize regions for repair. The same tool could be used to determine if radar absorbers around antennas are functioning properly and to locate anomalies. It could also be used for radar absorbing/low observable coatings for the same purposes.
