Background The U.S. Navy requires the ability to detect targets using recently developed low cost, low power consumption, high sensitivity solid state magnetic sensors integrated into unmanned underwater vehicles (UUVs). These magnetic sensors have the potential to provide the Navy with enhanced capabilities to detect low magnetic signature buried and proud targets particularly in the littoral zone. These sensors will also have the added capability to detect intrusions into secure coastal facilities. The University of Southern Mississippi’s Roger F. Wicker Center for Ocean Enterprise, located at the Port of Gulfport, MS has been researching and testing advanced uncrewed systems using sonar and magnetic sensor designs, and on-board processing to create advanced maps of acoustic and magnetic sensor data over a broad range of environmental and platform noise conditions. The University of Southern Mississippi (USM) has received funding to purchase several high resolution side scan sonar systems which will be integrated into a combined sonar/magnetometer tandem towed system. These systems will map the location of specific targets inside USM’s CUBEnet test range environment. II. Purpose The University of Southern Mississippi (USM) has developed the environmental measurement framework, data processing, visualization products, and ocean measurement system required for testing and performance evaluations of these new and emerging solid state magnetic sensors. This document contains the minimum requirements for two advanced side can sonar systems. This will include conventional and ultra-high resolution sonar systems and an integrated magnetometer. These systems will be integrated and tested to determine the ideal sensor configurations for detection, classification, and localization (DCL) of low/medium/high metallic strength targets over a broad range of environmental and platform noise conditions. The sonars systems will map the placement and types of proud and partially buried targets deployed in USM’s CUBEnet test range. III. General Requirements 1. Each side scan sonar towfish should be able to fully integrated to the magnetometer system to facilitate tandem and towing and data acquisition. 2. An automatic target recognition and display software shall also be provided which uses the native sonar file format and utilizes the full resolution raw sonar data for convolutional neural network (CNN) analysis. 3. Each towbody shall have an AMSTEELTM safety cable. 2 4. Splashproof topside processing units shall be included for each system. 5. Each of these systems shall be controlled by a rugged topside laptop. 6. A depressor wing shall be included for each system. 7. Each of the systems shall have a dedicated altimeter transducer for optimized bottom tracking. 8. The systems shall provide a method to minimize shallow water surface reflections. 9. Each of the systems shall come with its own transportation crates. 10. The vendor shall provide a list and cost of all optional onboard spares. 11. The vendor shall also provide a list of optional tow and deck cables. 12. To meet program requirements the side scan sonar systems, winches, and all supporting equipment shall be delivered to USM within 90 days after contract award. 13. The delivery arrangements and transportation costs shall be the vendor’s responsibility. 14. The side can sonar systems, towbody, and winch shall be delivered to USM’s Marine Research Center, 1030 30th Ave Gulfport, MS 39501. IV.
