【摘要】：当前世界,信息技术的高速发展使得其在军事领域中得到广泛的运用,由此引发一场世界范围内的新军事变革,高技术条件下的信息战作为一种全新的作战方式开始走上现代战争的舞台。在信息技术的支持下,以作战群为作战单位的联合已经成为未来作战指挥控制的主体,作战群的通信方式主要是以无线通信为主,因为无线通信具有不需要受线的限制,具有一定的移动性,虽然如此,在作战群存在着作战无线电台组织频谱利用率低、通信联络可靠性不高等问题,因此深入研究和解决作战群所面临的这些问题,对于打赢高技术条件下的战争至关重要。作战群面临的无线电台的频谱组织利用率低的情况,在民用领域也存在着相同的问题。面对这些问题,人们开始去探索新的频谱资源管理方式,以此来提高频谱资源的利用率。认知无线电[1](CR:Cognitive Radio)技术的产生使得无线通信设备拥有发现并合理使用“频谱空穴”的能力,并且对于频谱资源的利用率显著提升。鉴于此,本文采用CR技术来解决作战群存在的通信问题,主要做如下工作:一是总结提出了作战群无线电台通信运用的方法,研究了这些方法的结构示意图及其组织关系;组织无线电台通信基本方法,通常采用专向通信和网路通信。根据需要,还可以采取转信、通播、旁听旁抄、单方发信和遥控等方法;二是研究目前作战群无线电台组织运用方法中的问题,针对这些问题给出了相应的一些可能解决的途径;三是总结提出了作战群通信联络的双,主台和属台相互信任的协同频谱感知算法研究。并从性能分析、数值仿真等方面分析协同频谱感知算法。仿真的结果表明,在作战群完成体系的作战的过程中,组织无线电通信时,可以用认知无线电来组织通信联络,从而减少干扰、提高频谱利用率等。最后由认知无线电的频谱管理,将其引入到作战群的战场频谱管理中,提出了作战群短波信号频谱管理系统的框架,描述了作战群频谱管理详细流程,并以Chirp探测系统为例分析了作战群频谱管理的可行性。
[Abstract]:In the present world, with the rapid development of information technology, it has been widely used in the military field, which has led to a new military revolution in the world. The information warfare under the condition of high technology, as a new way of warfare, began to enter the stage of modern war. With the support of information technology, the combination of combat groups as combat units has become the main body of command and control in future operations. The communication mode of battle groups is mainly wireless communication, because wireless communication does not need to be restricted by lines. It has some mobility. However, there are some problems in the battle group, such as low spectrum efficiency of operation radio station organization, low reliability of communication, etc., so the problems faced by battle group are deeply studied and solved. It is very important to win the war under the high-tech condition. The low efficiency of spectrum organization of radio stations faced by battle groups has the same problem in civil field. In the face of these problems, people began to explore new methods of spectrum resource management to improve the efficiency of spectrum resources. The generation of cognitive radio (CR: Cognitive Radiotechnology) makes wireless communication devices have the ability to find and use spectrum holes reasonably, and the efficiency of spectrum resources is greatly improved. In view of this, this paper adopts CR technology to solve the communication problem of combat group. The main work is as follows: firstly, the methods of communication application of battle group radio station are summarized, and the structure diagram and organization relation of these methods are studied. The basic method of organizing radio communication, usually using dedicated communications and network communications. According to their needs, they can also adopt the methods of communication, broadcasting, side copy, unilateral communication and remote control. Second, it is necessary to study the problems in the current methods of organization and application of radio stations in combat groups. In order to solve these problems, some possible solutions are given. Thirdly, the research of cooperative spectrum sensing algorithm based on the mutual trust between the two main stations and the subordinate stations is proposed. The cooperative spectrum sensing algorithm is analyzed from performance analysis, numerical simulation and so on. The simulation results show that cognitive radio can be used to organize the communication in the process of the combat group completing the operation of the system, so as to reduce interference and improve the spectrum efficiency. Finally, the spectrum management of cognitive radio is introduced into the battlefield spectrum management of battle group, and the framework of the spectrum management system of battle group shortwave signal is proposed, and the detailed flow of spectrum management of battle group is described. Taking Chirp detection system as an example, the feasibility of spectrum management of battle group is analyzed.
