Sonar System Design and Analysis
Design of both active and passive sonar systems requires careful attention to the intended operational environment, desired detection ranges, classification metrics and system constraints such as source power and physical size.  Key elements of sonar system design include appropriately specifying source array and/or receive array properties, system bandwidth, and optimized sensor deployment.

Sample output from a design tool used to predict multistatic sonar performance for variations in sonar receive and transmit array properties and environmental properties.

At APS, we offer an extensive background in sonar system design and analysis.  APS also specializes in developing complete prototype sonar systems.  Because our corporate expertise includes all facets of sonar system engineering – including transducer design, signal conditioning, data acquisition, beamforming, detection, localization, tracking and classification – we provide a unique end-to-end system design capability.  Moreover, we have worked on systems intended to operate over a wide variety of spatial scales, from multistatic air-ASW to short range ultrasonic active sonar.

One of our more high profile projects is a diver detection system we are developing for the Department of Homeland Security’s Advanced Research Project Agency.  This innovative system will nominally cover a 1,000 ft x 1,000 ft inshore area at a cost of less than $100,000.   The specifications for the acoustic nodes that are being built for this project were derived in part from a high frequency, multistatic signal to reverberation model developed at APS.
