The Study And Implementation Of Safeguarding System For Submarine Campaign Based On ECDIS

This t hesis comes from the secondary development of a type of Electronic Chart Display and Information System (ECDIS).The submarine is primarily military strength of our naval. Along with the exaltation of science technique and equip technique, the enhancement of the antisubmarine ability, it takes higher request not only in military tactics but also in weapon technique. But during the attack of our submarine, the automatization degree of safeguard for campaign is not enough, this greatly influence battle effectiveness of naval.For the sake of better technique support and guarantee for submarine campaign, this thesis according to the request of navigation guarantee department of our navy, and aim at the characteristics of submarine campaign under modern condition, make the in-depth research about Safeguarding System for Submarine Campaign.By analysis the basic function request of the system, the total structure of the safeguarding system based on the ECDIS is built up. In succession, through deep study into the each tache of submarine campaign, the basic mathematical model of the system is established, such as the model calculating the moving elements of enemy target, the model calculating enemy target movement etc, based on these models, software is designed. Then, the error of calculating result is made qualitative analysis. At the same time this thesis studies the new calculating method based on Controlled Smooth Filter and the observability of parameter calculating method by Linear System Theory. In the end, by the support of ECDIS, we design and realize the Safeguarding System for Submarine Campaign.The manufacturing of the Safeguarding System for Submarine Campaign is now completed and realized in the ECDIS. We expect its more wide use in other ships in the future because of universal of the theory.
