Buried target detection with a synthetic aperture sonar

During SAX04 the NSWC‐PC dual‐frequency synthetic aperture sonar collected data from a buried target field. Detections of a buried fluid‐filled sphere from above critical angle averaged 34 dB and from below critical angle averaged 24 dB with a ripple field with predominant 42‐cm spacing. These results are compared to simulated PCSWAT results.
