PROSAS™ – Real-Time Synthetic Aperture Sonar Processor

View a report about our product demonstration.

Synthetic Aperture Sonar
SAS is a revolutionary underwater imaging technique that provides extraordinary area coverage, imagery, and bathymetry at high spatial resolution, for a fraction of the cost of conventional systems. PROSAS™ combines SAS technology with leading-edge automatic target recognition (ATR) and anomaly detection processing to provide high-quality seafloor surveillance.

	The first automated, full-swath, real-time synthetic aperture sonar (SAS) processor
	High-speed, high-resolution acoustic imaging system that coherently combines the returns from multiple pings to synthesize a large acoustic aperture
	System delivers sonar imagery with unprecedented resolution independent of range and frequency
Applications
	Seafloor mapping
	Economic exclusion zone mapping
	Mine hunting
	Long-range surveillance
	Maritime search and investigation
	Marine construction
	Oil and gas exploration
	Ecological/environmental survey
	Telecommunications and pipeline survey
Features
	Along-track resolution independent of range
	Over 25 times greater resolution at range with a 300% increase in area coverage compared to conventional sidescan sonar
	Applies to full range of sonars, from high frequency, short-range to low frequency, long-range anti-submarine warfare
	Inch-scale resolution to 500 yards, yard-scale resolution to 25 kiloyards
	Motion compensation, image formation, and auto-focusing algorithms
	Customization services allow interferometric, height-finding, and sub-bottom processing

Comparison of side-looking sonar and SAS image of a rock field. These images were processed during the Oslo sea trials. The SAS image provides greater clarity and allows for closer inspection of the clutter field to identify anomalous items.

	Modular – PROSAS is embedded within an adaptable middleware architecture, allowing users to specify a system that exactly meets their requirements. Modules include: ATR, anti-submarine warfare (ASW), mine hunting, and bathymetry.
	These PROSAS partners offer additional SAS system elements to provide tailored solutions: Edge Tech, Ultra Electronics, Triton Imaging, Inc., and Oceanic Imaging Consultants
	PROSAS imaging technology is used in the MINESCOUT workstation, which provides ATR for combined analysis of SAS, side-looking sonar (SLS), and non-acoustic sensor inputs from autonomous unmanned vehicles (AUVs) for mine detection
