摘要: DIS 作为一项现代仿真技术,在多兵种、多种武器平台的联合作战仿真与训练演习方面有着极其重要的作用,而DR技术是构造DIS系统的关键技术之一.本文首先介绍了采用DR技术的意义及特点,以及通常采用的DR算法.然后介绍一种本文采用的参数递推算法.这种算法基于二阶传递函数思想,含有自然频率和阻尼系数这两个特征参数,特征参数可由前三帧的状态值实时计算得到.文章最后对算法优劣进行了评价,并给出了仿真运行结论.

Abstract: A method of position/orientation estimation called dead reckoning methodology has been playing an important role in DIS system,which is employed to simulate synthetic warfare environment simulation and military training exercise containing multi-force and multi-platform. First,common DR algorithms and their characteristics are introduced,and then a new valid DR algorithm is presented in this paper. This algorithm is based on two-order transfer function idea and has two feature parameters,which are natural frequency and damper coefficient. The two feature parameters can be real-time calculated by previous state values of last three frames. Last of all,the comparison between the new DR algorithm and common DR algorithms is described and the simulation result is given at the end of this paper.
