Study on engine mechanism of radar system simulation based on distributed architecture

With the expansion of the scale and the promotion of the complexity of system, using the single simulation program has not been able to meet the demand of large-scale complex system and the method of radar system simulation based on distributed architecture becomes a solution for complicated system simulation. Study on the engine mechanism in distributed architecture is the key for the design of radar simulation and more conducive to deepen and improve radar simulation efficiency. This paper firstly expounded the radar simulation system model and then proposed two level control structures of simulation engine mechanism based on the message service center and runtime monitor center in distributed architecture in order to detach user interface service from message passing service and to enhance the flexibility and usability of radar simulation software. Under this mechanism, it put forward the message passing algorithm (MPA) and made the system performance test and verification. The simulation results show that MPA in this mechanism can fleetly and reliably realize the interconnection and communication between executable processes of radar simulation system and can accurately monitor the course of radar simulation.
