| This paper particularly and thoroughly studied the development of air situation simulation system on a certain military information system. Firstly introduce the system's frame and analyze the whole system by OOA technology, from which abstract some clusters and give the connection of these clusters, secondly give the arithmetic about plane's track, radar and sentry's scan function by thoroughly study the curve's fit and insert value method, show a better method for how to inspect plane, finally paint the system's flow chart. The system is basically credible by test. At present, it being used to the study and production of a certain large-scale martial information system . |
