Acoustic Array Simulation Environment System Navy SBIR FY2012.2 Sol No.: Navy SBIR FY2012.2 Topic No.: N122-108 Topic Title: Acoustic Array Simulation Environment System Proposal No.: N122-108-0862 Firm: Softronics LImited 1080 East Post Road, Suite 1 Marion, Iowa 52302 Contact: Robert Sternowski Phone: (319) 447-1446 Web Site: www.softronicsltd.com Abstract: ASW training requires an accurate simulation of both sonobuoy data content and geolocation in order to maintain peak crew proficiency. Unfortunately, existing systems can generate and emit the necessary field of 64 sonobuoy signal simulations, but without the geographic dispersion of a real sonobuoy pattern (which is an unaffordable training option and unrealistic/uncontrolled simulation scenario). Thus the crew cannot train with the direction finding and geolocation features of the ASW system. Given the physical impossibility of spoofing a TDOA DF system, Softronics instead proposes a system based on the existing SASSIE/RFSonosim sonobuoy simulators that remotes the RF transmitter portion of the RFSonosim via datalink. This breaks up the 64 simulated sonobuoy emissions emanating from a single location; any mix of single site and deployable land/sea nodes can be used, and dispersed as desired to provide ASW crews a realistic sonobuoy pattern training event. The RF nodes are small, reusable, low-cost, buoy-packaged, and fully remotely operated, with all of the sensitive acoustic scenario generation system safe on shore. Benefits: There is little commercial use for this system due to lack of use of DF in commercial radio work. The primary use is Government and military, primarily for ASW and SIGINT training. The system is deployable on the ground or on a ship, and can be transportable or permanently installed. We see Foreign Military Sales (FMS) potential, subject to ITAR restrictions. The resulting product is an accessory and/or derivative version of the Navy's RFSonosim sonobuoy RF simulator for all analog and digital buoys. Return
