Abstract

The invention provides a distributive data link communication testing system for a spread-spectrum system. The distributive data link communication testing system comprises a direct-spread data link signal emitter simulation element, a frequency hopping data link signal emitter simulation element, a channel simulation element, a direct-spread data link receiver simulation element, a frequency hopping data link receiver simulation element and a system control management member, wherein the system control management member is under a federation management mode for managing the operation of the whole federation, sending a control instruction and finishing the interaction state. According to the system, the HLA-RTI technology is carried out achieve synchronous communication and interaction of all elements, so as to ensure that all parts of the system are coordinated and sequentially operated; therefore, a stable and expandable data link communication testing system is constructed to perform simulation test for a signal emitter, a channel and a receiver of a data link communication system.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a distributed data link communication testing system oriented to a spread spectrum system. Background technique [0002] Spread spectrum communication technology has the advantages of low probability of being intercepted and strong anti-interference ability. It has become a key technology in data link communication system and has been widely used in the field of communication. Most of the existing data link communication systems test the functions of simple terminals, such as data link signal generation, transmission and reception, and do not control and manage the system from the perspective of state synchronization and time synchronization. Therefore, the correctness of the processing process and timeliness cannot meet the test requirements. Contents of the invention [0003] This application provides a distributed data link communication test system oriented to the spre...
