基于框架的联邦开发工具是快速开发HLA仿真应用系统的重要方式。HDOSE是一个基于HLA的支持软件重配置和模型动态表示的分布式交互仿真框架,其可伸缩的基于元模型的软件体系结构和高效的底层服务为应用系统的构建和演化提供了有力的支持。通过将仿真系统中对象的交互、对象的结构、对象的行为进行分离,并应用设计模式的原理提供通用的机制解决系统中的共性问题,使HDOSE具有最大程度的可复用性;简单易用的接口和实用的概念模型简化和方便了系统的设计和实现。实践表明,HDOSE是开发基于HLA的仿真应用系统的用力工具。

第四届国际微波与毫米波技术会议

作者： QU Changwen Huang Yong SU Feng He You(naval aeronautical engineering {3. Yantai 264001 P.R.china)

＜正＞In the background of K-clutter plus thermal noise, the performance of track-before-detect （TBD） algorithm based on Hough transform is analyzed detailedly and the analytical expressions of detection probability and false-alarm probability are given. Then the PadéApproximation （PA） method is used to approximately calculate these analytical expressions, which avoids complicated integral computation and conveniently finishes evaluating the detection performance. Lastly Monte Carlo simulation shows the feasibility of PadéApproximations.
