【摘要】：现代空战中的电子对抗日益激烈。各国专家都在研究如何提高战斗机的作战性能,与此同时,顺应时代需求的多机协同作战模式也被给予了越来越多的重视和研究。机载雷达作为战斗机的电子眼,在协同探测、协同干扰,协同抗干扰,协同攻击的过程中起着无可替代的作用。本文以武器装备的作战效能评估为出发点,研究了多机协同作战模式、机载雷达以及效能评估的相关理论,并在此基础上以Visual C++6.0为平台开发了一套效能评估软件系统。本文的主要研究内容为:1.根据目前及未来空战的特点,讲述了多机协同作战的意义,研究了多机协同作战的方式、协同作战的过程以及协同作战中所涉及的关键技术;探究了机载雷达的基本理论,提出了影响机载雷达作战性能的主要指标。从而明确了课题效能评估所要研究的目标,为课题的研究打下了基础。2.基于效能评估的相关理论,提出了多机协同条件下机载雷达作战效能评估的流程,通过调研并采取德尔菲咨询法构建了更加完善的多机协同条件下机载雷达作战系统的指标体系,并明确了定性、定量指标的规一化模型。3.介绍了几种被广泛使用的作战效能评估方法,针对传统灰色关联度中关联系数的计算受到方案样本量及分辨系数的影响,造成评估结果不一致的缺点,并结合处理数据类型的不同,提出了两种改进的灰色关联度模型,这两种模型分别用来处理指标数值为精确值和指标数值为区间数的系统的效能评估,通过实例验证了方法的可行性,为多机协同条件下机载雷达的效能评估提供方法。4.在明确效能评估目标、构建了目标指标体系、确定效能评估方法的基础上,以Visual C++6.0为平台开发了一套效能评估软件,介绍了效能评估软件开发的过程,总结分析了调试过程中遇到的一些问题,并演示了如何使用该软件进行效能评估。5.总结已经研究的内容,提出了工作中的不足并对以后的研究方向做出了展望。
[Abstract]:Electronic warfare in modern air combat is becoming increasingly fierce. Experts from all over the world are studying how to improve the combat performance of fighter aircraft while at the same time. More and more attention has been paid to the multi-aircraft cooperative combat mode, which conforms to the needs of the times. As the electronic eye of fighter, airborne radar is used in cooperative detection, cooperative jamming and cooperative anti-jamming. Cooperative attack plays an irreplaceable role. Based on the operational effectiveness evaluation of weapons and equipment, this paper studies the theory of multi-aircraft cooperative combat mode, airborne radar and effectiveness evaluation. On this basis, a software system of effectiveness evaluation is developed on the platform of Visual C 6.0. The main research content of this paper is: 1.According to the characteristics of present and future air combat. This paper describes the significance of multi-aircraft cooperative operation, studies the mode of multi-aircraft cooperative operation, the process of cooperative operation and the key technologies involved in cooperative operation. In this paper, the basic theory of airborne radar is explored, and the main targets that affect the operational performance of airborne radar are put forward. Based on the theory of effectiveness evaluation, the operational effectiveness evaluation process of airborne radar under the condition of multi-aircraft coordination is proposed. Based on the investigation and Delphi consultation method, a more perfect target system of airborne radar combat system under the condition of multi-aircraft coordination is constructed, and the qualitative analysis is made clear. This paper introduces several widely used operational effectiveness evaluation methods. The calculation of correlation coefficient in the traditional grey correlation degree is affected by the sample size and resolution coefficient of the scheme. Because of the inconsistency of the evaluation results, two kinds of improved grey correlation models are put forward in combination with the different data types. The two models are used to deal with the effectiveness evaluation of the system with accurate index value and interval value respectively, and the feasibility of the method is verified by an example. In order to provide a method for the effectiveness evaluation of airborne radar under the condition of multi-aircraft cooperation. On the basis of defining the target of effectiveness evaluation, the target index system is constructed, and the effectiveness evaluation method is determined. A set of efficiency evaluation software is developed on the platform of Visual C 6.0. The development process of efficiency evaluation software is introduced, and some problems encountered in debugging are summarized and analyzed. It also demonstrates how to use the software to evaluate the effectiveness of .5. summarizes the contents of the research, puts forward the shortcomings of the work and makes a prospect for the future research direction.
