Development of a Pipe Location System, Phase 2 and 3. Annual Report January 1983-April 1984

摘要

A high speed image reconstruction algorithm based on synthetic aperture focusing techniques was developed and tested. The system can reconstruct images within ten seconds after completion of a scan. Techniques were developed for radar imaging of plastic and steel pipes. Advanced acoustic methods were evaluated with limited success. Pipe farms at two sites in Washington will be used to field test the techniques.
