Final answer:
The subject of this question is Computers and Technology. Specifically, the question is asking about a system that exchanges radar picture data with other C2 systems and shooters via various tactical data link systems and obtains tactical data link information from other surface and airborne participants to expand or augment surveillance coverage.
Step-by-step explanation:
The subject of this question is Computers and Technology. Specifically, the question is asking about a system that exchanges radar picture data with other C2 systems and shooters via various tactical data link systems and obtains tactical data link information from other surface and airborne participants to expand or augment surveillance coverage.
This system is commonly used in military operations and is known as a Command and Control (C2) system. It helps in coordinating and sharing information between different participants in the battlefield.
Some examples of such C2 systems are the Link 16 and Link 11 tactical data link systems, which are widely used in military aviation and naval operations.
