Applied Signal Technology performs successful survey operation to locate downed plane off Santa Barbara coast
Applied Signal Technology, Inc. (AST), a market leader in advanced underwater imaging systems, recently assisted the Aqueos Corporation with a survey, using its PROSAS Surveyor synthetic aperture sonar (SAS) system to locate the wreckage of a small plane that crashed off the Santa Barbara coast on Sunday, April 19, 2009. Aqueos Corporation, formerly Divecon, is a leading subsea survey service provider.
PROSAS Surveyor has the ability to produce photographic-quality images in real time across the entire transmission range. This capability not only results in superior seabed imagery, but also in increased area coverage rates that allows for a faster, more efficient, and cost effective survey. The level of detail produced by PROSAS Surveyor enabled Aqueos to distinguish debris from normal sea clutter, thereby significantly reducing the number of false detections. As a result, Aqueos was able to pinpoint the location of the wreckage within hours of arriving at the search area.
Dr. John F. Pesaturo, Vice President of AST's Sensor Systems Division, said, "This deployment marks the first time that synthetic aperture sonar technology has been used for commercial underwater search activities The system's superior seabed imagery combined with high-precision navigation and geolocation features make it an ideal solution for large area survey applications. AST is pleased with the accuracy and the expedience in which PROSAS Surveyor positively identified the exact location of the plane."
