Distributed Radar System Simulation Applications

Computer software designs and realizable methods were introduced here to construct the software model of new radar system, to simulate operational flows of specific radar system with communications of scene generater, echo simulater, signal processer, resource scheduler, data processer, target recognizer, system controller, terminal display-controller and the like emulational members, to realize deep research and grope for related algorithms and techniques in the condition of different scenes setted. A universal software platform built and extended contributed to the digital closed radar simulated system with the least cost and the most important applicatable value.The dissertation firstly summarized characteristics of distributed system, educed the thinking of distribution into radar simulation, disserated distributed interactant simulation (DIS) and high level architecture (HLA) emphatically with the evolution of techniques in distributed interactant simulations and the status of researches. According as the characteristics of makeup in radar system, taking advantage of these two kinds of simulations, we brought forward the distributed software architecuture fitting in radar simulated system, developed XXX radar digital simulated system while making it perfect stage by stage. The research and development of distributed radar software simulated system would well be beneficial for the development of all-purpose digital radar simulated system. Main content-list researched here is:1. It generalized the advancement and research-status of techniques such as SEVINENT, ALSP, DIS and HLA in distributed interactant simulations, introduced an idea of distribution in radar digital simulated system after presenting and comparing DIS with HLA emphatically.2. It expatiated on the distributed radar simulated system, brought forward the thinking of hiberarchy in design of XXX radar simulated system and the software architecture, and then expatiated on the realizable patterns of software interface of radar simulated system.3. It expatiated on the designs and realizable patterns in the layer of display of radar simulated system. With the requirements of functions, it devised the module of system console, the module of display control system and etc. With the requirements of displaying, it devised the module of three-dimensional scenes which would reinforce and enrich two-dimensional display. The research of Java3D techniques applied to the developping of three-dimensional scene was discussed at the same time and finally the procedures of developping in three-dimensional scene were summarized also.4. It expatiated on the designs and realizable patterns in the layer of data of radar simulated system. The idea of data interface unification was introduced firstly, then the designs and realizable patterns in the layer of data were studied deeply from data definiting, data descripting, data parsing, data organizing and mapping, data generating, data serving interface and etc which was born of the idea of data interface unification, finally the research and test of writing method for matrix data was introduced and the optimized method for writing matrix data was summarized also.5. It gave the testing of radar simulated software system in the condition of scenario scenes, simulated the operational flows of radar and surveilled the whole course of tracing on targets while collecting the experimental data.
