Description

technical field [0001] The invention relates to the technical field of data links, in particular to a semi-physical simulation test system for data links. Background technique [0002] As a tool and means for the military command, control and intelligence system to transmit information, the data link is an important communication method in information warfare. In the digital battlefield, the command center, command posts at all levels, all participating troops and weapon systems are linked together through "data links" to form an integrated data communication network of land, sea, air and space. In this network, all kinds of information are transmitted and exchanged in real time, automatically and confidentially in accordance with the specified information format, so as to realize the sharing of information resources and provide the commander with a unified, timely and accurate combat situation in the entire theater for rapid and correct decision-making . [0003] Differen...
