Abstract:
This report summarizes activities in support of the DOT contract on Testing & Evaluating Close-Range SAR for Monitoring & Automatically Detecting Pavement Conditions & Improve Visual Inspection Procedures. The work of this project was performed by Dr. Don Atwood and Dr. Keith Cunningham of the University of Alaska Fairbanks with support of ImSAR, makers of the world’s smallest SAR, located in Springville, Utah. As described in the Team Project Activities document, the preliminary goals of the project were to: 1. Conduct a kick-off team meeting at ImSAR facilities in Springville, Utah. Review SAR sensor operation with ASF scientists, Yotta pavement engineer, and ImSAR engineers (hereinafter called the “team”). Review science methodology, labor expectations, equipment, facilities, and pavement test areas. Yotta pavement engineer identifies and documents test pavement and pavement conditions to be imaged near ImSAR facilities. ImSAR engineers work with ASF scientists to develop a mount for the ImSAR sensors on an ImSAR vehicle. Two days of image testing with X-band sensor and two days of image testing with Ku-band sensor. Collect documentation, experiment notes, and test results for future reporting. 2. Document sensor test methodologies and experimental results of pavement imaging with the two SAR sensors. Optimal use of the SAR sensors learned from this test for pavement imaging is documented based on the results of the tests conducted. Imaging data is forwarded onto supporting Yotta pavement engineers for their analysis of the imagery for pavement surface and crack detection. Additional experimental analysis is defined and documented by team, as necessary. 3. Summarize results of kick-off meeting, first round of SAR sensor experimentation, and resulting pavement imaging results to DOT in the first quarterly report within three (3) months of the effective date of the Agreement. 4. Be available for a possible presentation to DOT in Washington DC as part of a project summary and information sharing event.
