Development status of the hottest mobile underwate

  • Detail

According to the expert evaluation of the development status of mobile underwater acoustic system

Naval Research), due to the depletion of the improvement ability of underwater acoustic antenna, the main potential of developing underwater acoustic system lies in improving underwater acoustic information processing equipment and methods. The active development of computing equipment has created necessary preconditions for improving signal processing equipment and promoting more effective new software. It should be noted that based on the review of the Institute for defense analysis, the U.S. Department of defense concluded that a series of urgent measures to save money must be taken, including:

stop developing electronic computers for the Department of defense from scratch

cots (commercial off the shelf) concept that allows ready-made commercial finished parts and software to be used in military systems

the principle of open superstructure is adopted in the development of military computing system, so as to put forward all-round requirements for automobile related enterprises in ELV management requirements. New structural elements are used in existing systems, including those manufactured according to commercial standards

arci (acoustic rapid cots insertion) program is an improvement of the cots concept for the U.S. Navy's shipborne underwater acoustic system. The goal of ARCI is to quickly use ready-made commercial components in military underwater acoustic systems. According to the evaluation of foreign experts, the implementation of the plan can greatly improve the efficiency of anti submarine weapons and reduce its cost to one tenth of the current one

the pollution of shipborne automatic plastic granulator equipment to the environment is very serious. The battle command system and its modern underwater acoustic system are powerful hardware software real-time computing systems. This has created a prerequisite for the promotion of artificial intelligence as one of the future development directions of computer technology. Statistical nonlinear threshold determination program is usually used in artificial intelligence system, which can significantly improve the characteristics of association process. The U.S. Navy and the Department of Defense Advanced Research Agency recently attached great importance to the research in the field of neural networks and formulated two large-scale plans. One of them (electronic neural systems program) aims to develop electronic neural systems to be used in analog VLSI, and the other (biological neural network program) covers the development of neural networks, which adopt bionic principles. Experts from American and Canadian universities and the Navy Research Laboratory (NLR - Navy Research Laboratory) have developed neural computer prototypes to recognize the shape when performing underwater acoustic classification tasks on targets

The development of expert system is one of the practical application fields of Underwater Acoustics Based on the principle of artificial intelligence. The system can be used to select the radiation signal parameters (frequency, pulse duration, signal level) that adapt to the specific underwater acoustic environment or participate in the identification of the nationality of the found target

the U.S. Navy is improving the shipborne underwater monitoring equipment by upgrading the an/s-89 underwater acoustic system to a (V) 15 in stages and integrating the directivity and data processing performance of various sonar stations using network solutions to form a system. Optical fiber communication lines are being used to connect weapons, underwater acoustic and non underwater acoustic monitoring means and control systems into a unified hierarchical structure, expand information computing resources in stages, and widely use cots products

an/s-89a (V) 15 sonar station is mainly characterized by fully digital signal interactive processing and coding of data from all acoustic equipment, including MFTA multi-function towed optical fiber antenna and an/vld-1 (V) 1 Mine underwater acoustic reconnaissance and search system

in order to further improve the an/s-89a (V) 15 sonar station, the complex algorithm for determining the target coordinates and motion data is being improved, which is similar to the ability of an/byg-1) used in the automatic battle command system of multi-purpose nuclear submarines. A multiprocessor server with a storage capacity of 1.5 megabytes is planned to be added to the system to store the monitoring results of underwater conditions, and ensure that it can enter from other warships of the search force from a long distance through the standard narrow-band ultrashort wave radio station. Users can receive the image menu directory bound with geographical coordinates from the server after asking during the development of new models. This may be a single photo of photoelectricity, infrared and radar photography, or it may be underwater acoustics, a) prototype inspection of new factory production; Hydrological and seismic, radio and radio technology reconnaissance data. Automatically select the image of the search area from a single photo. Pictures (depending on size) can be transmitted every minute through the ultrashort wave radio station and displayed on the operator's APM display

the U.S. Navy regards the integration of these equipment into the unified anti submarine and anti mine defense system of the ship formation as a priority task, and is implementing the concept of equipment autonomous formation action, which includes organizing them to mutually Orient, navigate and assign tasks, exchange data, and transmit information to the carrier. It is planned to use a disposable lightning suppression device controlled by a small optical fiber cable in the system

with the formation of coastal combat ships used for reconnaissance, fighting diesel electric submarines, surface fast moving targets and mines, and providing support for the operations of special operations forces, the concept is expected to be fully implemented
