technical field

Background technique

The real-time simulation of the data link situation is mainly used in the tactical exercise environment of the land, sea and air battlefield, simulating the target situation information of the enemy and the enemy in the battlefield, such as target type, position, speed, acceleration, direction, etc., to share the target situation information in the combat network and coordinate the operation. Real-time simulation of data link situation and mutual communication and information sharing between multiple weapon equipment units to 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 transmission characteristics of high frequency and high bandwidth, determine that the simulation of the data link system must require high real-time performance. In order to achieve real-time simulation of the data link situation in a full sense, a large amount of data link equipment and the real battlefield environment are needed as simulation conditions, which consumes a lot of manpower and material resources.

In the traditional data link situation simulation, the function of the data link terminal is generally replaced by a virtual prototype, the function of the data link terminal is simulated by software, and the battlefield environment is simulated by situation simulation software, thus forming a fully virtual digital simulation. But the disadvantages of this simulation are:

(1) The data link terminal machine simulated by software has poor real-time performance and cannot reflect the high real-time characteristics of coordinated operations;

(2) The software simulation cannot consider the influence of the actual transmission channel on the communication quality;

(3), the results cannot describe the battlefield application well, which is far away from the measured results;

In order to ensure the real-time performance of system simulation, it is often necessary to introduce some real objects into the simulation loop with the help of some hardware carriers, and replace some high-complexity and high-precision simulations with real objects. It is necessary to improve the simulation speed through distributed simulation and accelerated simulation methods. On the one hand, it is necessary to maintain the synchronization and consistency with the physical simulation.
