Description

Technical Field

[0001] The invention belongs to the technical field of data link situation real-time simulation, and in particular relates to a virtual-real combined data link situation real-time simulation system and method. Background Art

[0002] Data link situation real-time simulation is mainly used in the tactical exercise environment of land, sea and air battlefields. It simulates the target situation information of both sides in the battlefield, such as target type, position, speed, acceleration, direction, etc., shares the target situation information in the combat network, and coordinates the command of operations. Data link situation real-time simulation and mutual communication and information sharing between multiple weapon equipment units can achieve more efficient overall combat effectiveness. The multi-body coordination and multi-mode composite business characteristics of the data link system, as well as the high-frequency and high-bandwidth transmission characteristics, determine that the simulation of the data link system must require high real-time performance. If you want to achieve real-time simulation of data link situation in a complete sense, you need a large amount of data link equipment and a real battlefield environment as simulation conditions, which consumes a lot of manpower and material resources.

[0003] Traditional data link situation simulation generally replaces the functions of the data link terminal with a virtual prototype, simulates the functions of the data link terminal with software, and simulates the battlefield environment with situation simulation software, thus forming a fully virtual digital simulation. However, the disadvantages of this simulation are:

[0004] (1) The real-time performance of the data link terminal simulated by the software is very poor and cannot reflect the high real-time characteristics of coordinated operations;

[0005] (2) Software simulation cannot take into account the impact of the actual transmission channel on communication quality;

[0006] (3) The results cannot describe battlefield applications well and are far from the actual measured results;

[0007] In order to ensure the real-time performance of system simulation, it is often necessary to introduce some physical objects into the simulation loop with the help of some hardware carriers, and replace some high-complexity and high-precision simulations with physical objects. For the non-physical parts, in order to match the simulation with the physical objects, it is necessary to improve the simulation speed through distributed simulation and accelerated simulation, and on the other hand, to maintain synchronization and consistency with the physical simulation.
