中文摘要： 在现代社会中决策信息的获取至关重要，无线传感器及无线传感器网络在这一领域的应用也愈加广泛，而无线传感器网络资源受限的特点与在复杂环境下高效、稳定的获取决策信息的要求存在矛盾。为了解决这一问题，本项目将在信道杂波分布形式不典型，系统参数信息不确定，传感器能量受限的情况下研究无线传感器网络的决策信息融合问题。研究非高斯杂波信道下的决策信息传输模型，并在此基础上推导无线传感器网络的决策信息融合规则；研究系统参数信息不确定条件下的系统参数估计方法，并利用这一方法对决策信息融合规则中的相关参数进行修正，保证决策信息融合性能；研究无线传感器能量分配与决策信息融合性能的关系，提出无线传感器网络能量分配策略，在决策信息融合系统的性能与传感器的工作寿命之间寻求平衡点。本项目意在为复杂环境下资源受限的无线传感器网络决策信息融合提供有效的方法及理论支持。

英文摘要： It is very important to obtain decision information in modern society, and the wireless sensors and wireless sensor networks are widely used in this field. However, there exists a contradictory between resource-constrained of wireless sensor network and requirements of obtaining decision information efficiently and stablely in complicated environment. In order to solve this problem, the decision information fusion issues of wireless sensor network will be researched in the case of atypical distribution of channel clutter, uncertain indices of system and energy constrained of sensors in this projection. The decision information transmission model of non-gaussian clutter channel will be researched, and the decision information fusion rules will also be derived. The study of estimation methods of system indices will be made in the case of uncertain inforamation of system indices, and modify the system indices using these methods to guarantee the performance of dicision information fusion. The relationship sensors' energy allocation and decision information fusion performance will be studied, energy allocation strategy of wireless sensor network will be proposed to seek the balance point between performance of decision information fusion system and life of sensors.The conception of this project is to provide effecti
