Description

technical field [0001] The invention belongs to the technical field of simulation, and in particular relates to a terrain modeling method and system for radar terrain imaging simulation. Background technique [0002] In the simulation system, the environmental data directly affect the performance of the simulation system. Different simulation systems are usually in the same physical environment during simulation, and the environment includes terrain, ocean, atmosphere, etc. The quality of the environmental data model directly affects the realistic experience of the simulation system. In the composition of the simulation system, there are two heterogeneous problems: (1) different training systems and (2) different subsystems in the same training system. There is usually data interaction and synchronization between these systems. Traditional simulation systems use independent databases, which will lead to problems such as poor data consistency, limited synchronization and data...

Problems solved by technology

The quality of the environmental data model directly affects the realistic experience of the simulation system. In the composition of the simulation system, there are two heterogeneous problems: (1) different training systems (2) different subsystems in the same training system

There is usually data interaction and synchronization between these systems. In the traditional sense, simulation systems each use independent databases, which will lead to problems such as poor data consistency, limited synchronization and data interaction of heterogeneous systems, and repeated development of databases.
