Mine & Mine Countermeasures
Wednesday 10th November 2010, 1100hrs–1230hrs
Chaired by Kunio Fujisawa Application and Research of GPU to the Marine Environment Based on Real Sonar Comprehensive Training Simulation System Mr. Dong Liping, Institute of Acoustics, Chinese Academy of Sciences, China Feng Shijun/ Li Qihu, Institute of Acoustics, Chinese Academy of Sciences, China The high processing power, parallelism and programmability available nowadays on the GPU and the rapid development of GPU in recent years at a speed over Moor’s law have created a research hotpot in general computing. Most of underwater signal processing tasks have the significant features of simple parallel processing flows and comparatively heavy computing burden. We design a GPU&CPU test system (4-cores CPU & 2 GPU chips). Additionally, we test the validity of this processing architecture for underwater signal processing. Meanwhile, we make use of the GPU & CPU system implementation of the marine environment based on real sonar comprehensive training simulation system. Autonomous Maritime Mine-Sweeping System for Disposal of Influence Mines Dr. Jan Tadeusz Dobkowski, R&D Marine Technology Centre (CTM), Poland Henryk Chodkiewicz PhD, R&D Marine Technology Centre, Poland; Aldo Pizzini M.Eng, Siel Sistemi Elettronici, Italy MCM operations, in particular on Shallow Water and Very Shallow Waters, always cause many problems. The use of MCM vessels, even equipped with the newest mine detection systems is posing a severe danger to those units, because the probability of mine detection, including mines buried in bottom sediments, doesn’t exceed 50%. In search of functional solutions to the problem, light magnetic acoustic sweeps Mk-105 type, towed by helicopters (USA), or small non-magnetic ASV were developed. Minesweeping systems towed by helicopters are constrained by the necessity of achieving small towing drag and power requirements, which in consequence lead to proposing very simple constructions, unable to generate fields with time-spherical (spatial) layouts corresponding with the signature of the ships equipped with the degaussing systems. In the last few years, the new multi-influence acoustic-magnetic sweep was developed and commissioned within the Polish Navy. This system is suited for towing by minesweepers or non-dedicated ships meeting suitable requirements (for example towing power, electric supply). Similar solutions named Smart MCM system are proposed by the SAAB Company (Tieto Saab Systems OG) and Saab Denmark AS. Further development of such minesweeping systems, presented in this paper, focuses mainly on:
accurate imitate of constant and alternating magnetic and electrical fields different classes of ships;
integration of magnetic and acoustic field generators into one minesweeping system;
ASV – towing minesweeping system on assigned trajectory with the possibility to alter parameters of towing and field generation during missions. Mine Counter Measures Systems Architecture Mr. Loïc Tacher, DCNS, France Nowadays, Mine CounterMeasures are envisaged through all the more automated systems, like UUVs, USVs, or even UAVs, carrying a variety of payloads. Many candidate systems, and many potential environmental and operational situations, cause the capability planner a combinatory situation. Developing a Mine CounterMeasures capability is choosing among a variety of systems and binding them into a coherent architecture, able to cope with planned operational scenarios. This paper will develop the architectural aspects of future Mine CounterMeasures systems generation. In other words, it depicts generic candidate architectures and discusses their effectiveness against technical feasibility and operational scenarios.
