The Distributed Simulation Platform And Key Technology Research For Air-defense Weapon System

In this paper, the modeling and simulation technology was introduced into the air-defense weapon system research field, the air-defense weapon system simulation platform was constructed, and the main analysis methods and tools were provided for the air-defense weapon system's experiment, evaluation, training and application.The air-defense weapon system simulation platform is a system which simulates an air-defense weapon with the homology in functions and similarity in construction among main equipments, taking its brief functions of the equipments not the certain type equipment as the simulation analysis object according to the analysis conclusions for different types of air-defense weapon systems. In this simulation system, the main functions of air-defense weapon system are achieved in the nodes which are real-time and distributed in computer network which comprise many personal computers, the information transfer and processing were realized via distributed network, assigning the simulation of main equipment function to the master-slave computer structure which take the network computer as the kernel node, the simulation experiment system was constructed in which the function model could be changed according to different weapon's model and the relative stable man-machine interface.The main contents involved in this paper are:1. To meet the demands on construction of the air-defense weapon system simulation platform, the necessity and practicability of establishing versatile, real-time, distributed simulation platform were discussed, built a simulation system framework which can be suitable for lots of fire-control system models such as separate style and two units in a system, set up a information model for simulation running control and simulation experiment within the simulation system. We also set up a shoot evaluation model of typical object movement tracing model and network simulation environment by means of analytic form, and studied the techniques of creditability verification for simulation platform.2. We studied and designed for the designing ways which involved in distributed simulation basic framework based on HLA/RTI, TCP/IP protocol and Socket programming, designed HLAFacility on the basis of HLA with object model technology aimed at the developing simulation application based on HLA/RTI, which increased the developing efficiency for simulation application based on HLA/RTI.3. This paper has analyzed the mathematical principle of 3D real-time imaging techniques and explained the factors which reduce the real-time ability. For the simulation of laser range-measurement system with single-handle tracing style based on collimator view, we put forward a versatile simulation model for collimator view, and accomplished the system design and implement For the environment simulation when small caliber air-defense weapon aimingstraightly, we bring forward a designing technique about versatile tracing training and evaluating system based on computer 3D real-time imaging techniques, and established a virtual artillery and hitting model. This paper also discussed the main issues which effect the real-time creating and display of figures and images, that is, simulation object modeling, multitask parallel handling for operating system, etc.4. Taking the versatile radar equipment system as researching filed, we put firstly forward and set up the system structure of the versatile radar equipment simulation system in field project and application field project. With the PLSE method and principle, the public resources in radar equipment simulation training filed were developed which could be reused by the numbers, the developing platform of simulation training system aimed on versatile radar equipment simulation training field was built, and the application project model based on platform also be constructed.5. We put forward the design concept of multi-mode tracing system simulation. By taking the typical fire-control radar as object which concentrates the television tracing unit, laser range measurement unit, and...
