在对海军作战仿真中水下探测和水声对抗功能需求、仿真实体类型和实体颗粒度进行界定的基础上,基于GBB技术,构建了水下探测和水声对抗模型体系,设计了与GBB数据表交互的数据结构及交互方式,并进行了实现.以此给出了在一定作战态势下,水下探测和水声对抗的实例分析.证明该水下探测和水声对抗设计可作为海军作战仿真系统的重要组成部分,合乎水下探测和水声对抗训练的需求.

城建档案是城市建设总体规划和具体规划的基础，也是城市规划、建设、管理维护等活动的重要凭证和依据，更是城市自然面貌、地质状况、建筑物和地上、地下管线的真实记录。随着城市建设的不断发展。在荆门市城市规划、建设和管理过程中产生了大量城建档案，这些档案是城市文明发展程度和水平的真实记录和写照，在城市经济、社会文化和城市建设中发挥了重要的作用。

The scope of shooting range scatter should be considered in the guidance process of wire-guided torpedo to ensure it entering into the area,where torpedo can implement effective homing to target.Based on the needs for the simulation of operation platform,operational effectiveness evaluation for equipment,and development of weapon operational method,this paper analyses the reasons why the scatter of wire-guided torpedo happens with a consideration of different control and guidance modes.The position scatter can be divided into the shooting range scatter and the ship scatter and the former is primary.Therefore,some mathematical models in three aspects of shooting range scatter are established,and the error scopes of range,horizon and depth are calculated.According to the above results,it is concluded that the scope of position scatter in the guidance process of wire-guided torpedo is a flat elliptical sphere.

Target threat estimation is beneficial to distributing battle resources of a war and can be used to draw a conclusion scientifically, in order to not only preserve better ourselves but also effectively hit enemy. Improving AHP method with fuzzy synthesis estimation can raise the accuracy and science of judged matrix. Estimating the submarine’s target threat coming from underwater and surface with modified AHP method, you can get the quantification result that the objective threatened. Modified AHP method can be used to estimate the threat grade of other type objectives. In order to raise accuracy much more, the value given by experts can be different when passing fuzzy judgment, but the specific property to judge the matrix remains further research.
