【摘要】：近年来,随着我国无线电通信技术的快速发展,无线电作为一种信息的载体,在国民经济建设中和国防建设中起着越来越重要的作用。目前,随着无线电发射设备使用数目的不断增加,频谱覆盖密度的持续提高,电磁环境的进一步恶化,在有限的无线电频谱资源越来越稀缺的情况下,频谱监管工作显得越来越重要。无线电监测部门为了能够准确地查找和排除干扰源以确保通信畅通,加强对于干扰源或非法电台的查处力度势在必行。本文在研究无线电干扰源的定位技术时,主要围绕着基于网格化频谱监测结果的无线干扰源的定位,主要工作包括:(1)通过在二维截面自由空间中,建立无线电的传播模型,根据多个监测点所监测获取到接收功率的大小,对干扰源的定位进行理论求解,并通过仿真实验进行验证。(2)提出了在二维截面自由空间中无线干扰源的定位算法。在二维截面自由空间中,通过设立多个无线电频谱监测点,利用多个监测点所监测获取到接收功率的大小,根据本文所提出的在二维截面自由空间中无线电干扰源的定位算法,推测出干扰源的具体位置,并通过仿真实验进行了验证分析。(3)提出了基于网格化频谱监测结果的无线干扰源的定位算法。在一片加入高斯白衰落或瑞利衰落的待测区域中,设有若干个矩阵排列的无线电监测器,构成一个无线电监测网,用于监测该区域干扰源信号的强度,测出其接收功率的大小,通过对于无线电监测器接收功率的大小进行分析,根据无线电监测器监测的数据,利用本文给出的算法来推测出干扰源所在的区域,并通过仿真给出了验证。(4)对于本文提出的基于网格化频谱监测结果的无线电干扰源定位算法,进行了进一步的改进,充分利用了每个监测器所监测到的数据,提高了无线电干扰源定位的有效性,并通过仿真给出了验证分析。
[Abstract]:In recent years, with the rapid development of radio communication technology in China, radio, as a carrier of information, plays an increasingly important role in the construction of national economy and national defense. At present, with the increasing use of radio transmission equipment, the continuous increase of spectrum coverage density, and the further deterioration of electromagnetic environment, the limited radio spectrum resources are becoming more and more scarce. Spectrum regulation is becoming more and more important. In order to find and eliminate the interference sources accurately to ensure the smooth communication, it is imperative for the radio monitoring departments to strengthen the investigation and punishment of the interference sources or illegal radio stations. This paper focuses on the location of radio interference sources based on the results of gridding spectrum monitoring. The main work includes the establishment of radio propagation model in two-dimensional cross section free space. According to the magnitude of the received power obtained from multiple monitoring points, the location of interference source is solved theoretically, and the algorithm of wireless interference source location in two-dimensional cross-section free space is proposed by simulation experiments. In the two-dimensional cross section free space, by setting up multiple radio spectrum monitoring points and using multiple monitoring points to monitor the received power, the location algorithm of radio interference source in two-dimensional cross section free space is proposed. The location of the interference source is inferred and verified by simulation experiments. (3) an algorithm of wireless interference source location based on gridding spectrum monitoring results is proposed. In a region to be tested with Gao Si white fading or Rayleigh fading, there are several radio monitors arranged in matrix to form a radio monitoring network for monitoring the intensity of the interference source signal in the region and measuring the magnitude of its received power. By analyzing the receiving power of the radio monitor, according to the data monitored by the radio monitor, the region of the interference source is deduced by using the algorithm given in this paper. The simulation results show that the proposed radio interference source location algorithm based on gridded spectrum monitoring results is further improved, and the data of each monitor is fully utilized. The effectiveness of radio interference source location is improved, and the verification and analysis are given by simulation.
