The thesis is classified into five chapters and contents are outlined as follows : in chapter 1 , an introduction is first given to the general principles and function model of information fusion . and then , fundamental issues about target tracking and architectures of multiple sensors target tracking system are presented . the development and status of information fusion and target tracking are reviewed 介绍了信息融合的基本概念和功能模型;介绍了目标跟踪的基本概念以及多传感器融合目标跟踪系统的结构;介绍了信息融合及目标跟踪领域的发展概况及研究现状;介绍了本文的内容安排和主要研究成果。
As a new and developing crossed discipline , study of information fusion aims to how to combine information from multiple sensors and other associated sources such that the resulting estimation and inference is , in terms of precision improvement and uncertainty reduction , better than would be possible if any of these sources were used individually 信息融合作为一门新兴交叉学科,其研究目的是如何通过综合多信息源的信息获得比依靠任何单个信息源更加准确和更加确定的估计与推理。
How to measure exactly the coal mass of pulverizer in fossil power plant ? it is one of primary causes that the efficiency of milling control is low and the automation is difficult to running . in this paper a method of solving uncertainty problem - evidential theory was studied principally from the view of the multiple sensor information fusion 火电厂中钢球磨煤机筒内存煤量的测量问题一直是制粉控制效率低和自动控制难以投入运行的主要原因之一,本文从多传感器信息融合的角度出发,重点研究了一种解决不确定性问题的有力方法? ?证据理论方法。
This is due to the following two facts : the ill - posedness induced by the incompleteness of the observation data can make the solving much more difficult ; in addition , the observation system involved multiple sensors are required to compensate the inaccuracy of the observation equipment , which will inevitably make the cost of the computation prohibitively expensive 这是因为,一方面,由观测数据的不完全性等因素导致的病态现象往往会给逆问题的求解带来很大困难;另一方面,由于观测设备自身性能和观测环境等因素的限制,要获得更高的估计精度往往需要用多个传感器对目标进行观测,这必将给求解逆问题带来由于计算量过大而难以实现的困难。
Given the condition of the fusion tracking under multiple sensors non - linear measurements , this paper applies the conclusion of the analysis of single sensor decoupled cmkf , tss filter and tss variance to the fusion tracking system . it also studies their application in basic measurement fusion and track fusion algorithm , and covariance recursive formula of track fusion is deduced . which offers a new way for steady - state performance evaluation of multi - radar fusion tracking 考虑多传感器非线性观测下的融合跟踪,论文将单传感器解耦cmkf 、 “暂稳态”滤波器以及“暂稳态”方差分析的结论推广应用到融合跟踪中,研究了其在基本的量测融合和航迹融合算法中的应用,推导了航迹融合中互协方差的递推公式和“暂稳态”公式,为多雷达融合跟踪的稳态性能估计提供了一种新途径。
