Research On Technology Of Integrated Organization And Synthetic Display For Satellite Marine Environment Information

At present, our country’s marine rights face many threats. Objectively, the need ofnaval information is increasingly urgent. The satellite information has the advantages ofcovering a wide range, out of national sovereignty space limitation, all-weathermonitoring and has become a main data security of marine information combat. Thesatellite marine environment information has the features of variety, complex structureand large amount of data. Its efficient organization and synthetic display are thedifficulty and key point of combat applications. Among them, the former is the datafoundation, and the latter is the key of application. This paper launches research aroundtwo key technologies. The main contents are as follows:An information integrated model and layer organization of the satellite marineenvironment based on combat tasks is established, for the efficient organization ofsatellite marine environmental information. The paper associates combat task withsatellite marine information, establishes the integrated data model, which can beeffective to provide operations with environmental information. Based on structurecharacteristics of the combat mission and environmental information level the papergives a model layer organization of the satellite marine environment based on combattasks, so as to provide the concrete operations levels with minimum data set. It isverified that this method improves the information transmission efficiency and systemservice performance.A triangle collapse model simplified algorithm based on weighted vertex vector isput forward, for the complex3d marine environment embedding a lot of models leads tothe problem of decreasing efficiency. The algorithm optimizes the efficiency andeffectiveness of model simplification, from triangular folding determination, thedetermination of folding candidate point position and the whole grid division threeaspects. It is verified that this method has the advantages of small amount of calculation,high simplified efficiency and effectively maintaining model external features.A dynamic military mark generation and control algorithm based on Cardinalcurve is brought out, for the problem of generation and control of military mark insynthetic display. This paper puts forward a dynamic military mark generationalgorithm based on Cardinal curve, which reduces the difficulty of dynamic militarymark fitting control points. The method based on parameter control is a very goodsolution to solve the problem of dynamic military mark shape to control. Experimentsshow that the method is very good to meet the demand of the generation and controlof military mark.A satellite marine environment information display prototype system is designedand implemented with thesis theory of the paper. This system verifies that thesis theory of the paper is feasible, valid and correct.
