【摘要】 海战场综合电子信息系统是海军作战的关键装备和技术保障，因此对海战场综合电子信息系统效能评估也就尤为重要。它既是为指挥机构提供决策的科学基础，也是为研究院所改进系统性能的主要依据。信息可用性向量是综合电子信息系统作战效能的重要指标，信号处理模型直接关系到综合电子信息系统信息可用性向量。本论文选择了对信号处理效果的评估方法进行研究，并提出了互相关评估准则。 相关算子在最佳接收机的设计、信号检测、数字水印、匹配滤波器的设计和分析中得到了广泛的应用，但这些应用无一例外都是针对确定性信号而言的。本文中的互相关准则是以相关算子为理论依据，以相关函数、相关系数为评估指标。互相关准则可以评估非确定性信号的处理效果，也可以评估干扰和抗干扰效果。在针对电子信息系统中的非确定性信号处理评估中，标准测试信号的选取是关键，本文介绍了标准测试信号选取的理由和依据。以Matlab为仿真工具评估信号处理的效果，对比最小误差准则、最小均方误差准则、信号谱分析、互相关准则评估结果。互相关准则是一种归一化、定量的时域评估方法。互相关准则以相关函数和相关系数为性能指标，互相关准则可以反映实际输出信号和理想输出信号的相似程度，其归一化的相关系数可定量的评估不同信号处理设计方案的差异。本文还介绍了评估电路的设计原理，在高频电子线路设计中遇到的困难和解决办法。更多还原

【Abstract】 The naval battle synthesizing electronics information system is a critical equipment for navy battle and a guarantee of technique, so it is particularly important to evaluate the efficiency of the naval battle synthesizing electronics information system. It is not only the science foundation for the command organization to make decision, but also the basis for the institute of research to improve the performance of the system. The information usable vector is the most essential index of the battle efficiency of the synthesis electronics information system and its model of signal processing is directly connected with its information usable vector. In this article, I choose to study the evaluation methods of the efficiency of the models of signal processing and put forward the evaluation criterion of cross correlation.Correlation operator is widely used in the field of designing the best receiver, signal checking, digital watermark, designing and analyzing matching filter, but all these applications are aiming at the certain signal. In the title, the criterion of cross correlation takes the correlation operator as its theory basis and correlation function and correlation coefficient as its evaluation index o It can be used to evaluate the processing efficiency of uncertain signal and the efficiency of jamming signal and anti-jamming signal as well. In the process of evaluating uncertain signal processing in electronics information system, the selection of standard test signal is the key. This introduces the reasons and basis in selecting standard test signal. It applies Matlab tool to evaluate the efficiency of signal processing and contrasts results of the minimum error rule, the minimum average square error rule, analysis of signal spectrum, evaluation of cross correlation criterion. Cross correlation criterion is a kind of unitary, quantitative time domain evaluation method. With the performance indexes of correlation function and correlation coefficient, this criterion can reflect the degree of the similarity between the practical output signal and the ideal output signal. Besides, its unitary correlation coefficient can qualify the difference among the evaluation of differentkinds of signal processing methods. This paper also introduces the principle of designing the evaluation circuit, analyzing the difficulty one often meets in the course of designing a high frequency electrical circuit and giving its solution.更多还原
