The Multi-threaded Interaction Technology For Distributed Simulation Of Radar Network

Radar network simulation is an important part of the evaluation for the performance of radar network. Distributed simulation architecture of radar network can display the comprehensive real-time situation of radar network simulation that has important effect for the evaluation for the performance of radar network. To solve the interaction problem of distributed simulation architecture, it is significant to design multi-threaded interactive interface which can implement concurrent communication.For the requirement of radar net evaluation, in this paper, we research the whole architecture and interaction technology of distributed radar net simulation. First, we put forward a kind of radar net distributed simulation architecture including four modules that are radar net simulation, intervention for simulation process, situational analysis for single node and overall net observation respectively. Secondly, based on QualNet simulation software, we introduced a kind of model of radar detection modeling theory and extension design, it can reasonably simulate the working process of the radar station. Then, we proposed a multi-threaded real-time interactive interface, this interface can realize the concurrent processing mechanism and information interaction of net simulation server, it can meet the interaction demand of distributed simulation architecture. Finally, for implementing the three modules including intervention for simulation process, situational analysis for single node and global net observation, we use Qt graphical interface development framework to design a set of radar net simulation interaction software.In this paper, distributed simulation architecture of radar net and multi-threaded interaction interface are tested. The test results show that the distributed simulation architecture of radar net can realize the intervention for radar net simulation process, single node intelligence analysis and the observation for overall radar net situation. Multi-threaded interactive interface can realize the concurrent processing mechanism of net simulation server and the real time and reliability of communication. The above technology research provides a reliable technical support for radar net performance evaluation and reliable approach for netted radar parameters and system optimization.
