【摘要】：有源雷达由于自身发射的电磁波信号易于被侦察和截获而容易遭受电子干扰和反辐射导弹的攻击,不同于此,外辐射源雷达借助第三方辐射源来完成对目标的探测、定位与跟踪,具有反隐身及低空探测能力,且抗干扰能力强、隐蔽性能好,成为雷达领域的研究热点。本文对外辐射源雷达数据处理的实时实现技术进行了系统研究,所取得的主要研究成果为:1.对外辐射源雷达数据处理算法进行了研究。介绍了基于球面相交(SX)算法的无源定位方法、航迹处理相关理论以及不敏卡尔曼滤波(UKF)算法,在此基础上,提出了一种基于聚类的数据处理方案,并通过仿真数据验证了方案的可行性。2.对外辐射源雷达数据处理算法的C/C++实时实现进行了研究。借助性能与易用性俱佳的开源矩阵库Armadillo来将相应的数据处理算法从Matlab代码平滑过渡到C/C++代码,依据一些常用线性数据结构的特点,选取并确定程序所需的各种数据结构,在此基础上进行既定算法的实时实现,并通过对多个频点数据的处理验证了所实现程序的实时性能。3.对雷达显控终端开发及航迹的回放显示进行了研究。结合实际工程需要,提出了基于微软基础类库(MFC)的雷达显控终端实现方案,通过不同组别的菜单选项,实现灵活的用户交互功能;给出ADS-B民航航迹的解析提取方法,设计并实现回放航迹结构,最终采用软件定时器驱动模式进行航迹的回放显示。4.对多雷达间的数据传输进行了研究。将多传感信息融合技术应用于多外辐射源雷达系统是进一步提高其定位性能的有效措施,在此之前,需要首先解决多站间的数据传输问题。鉴于此,提出了一种基于3G无线网络的数据传输方案,通过数据传输的收发测试,验证了传输的实用性,为下一步基于多雷达数据融合的组网探测打下基础。
[Abstract]:Active radar is easy to be attacked by electronic jamming and anti-radiation missile because the electromagnetic wave signal transmitted by itself is easy to be detected and intercepted. Different from this, external emitter radar uses third party emitter to complete target detection. Location and tracking, with anti-stealth and low-altitude detection ability, strong anti-jamming ability, good concealment performance, has become a research hotspot in the field of radar. In this paper, the real time data processing technology of external emitter radar is studied systematically, and the main research results are: 1: 1. The data processing algorithm of external emitter radar is studied. In this paper, the passive location method based on spherical intersection SX algorithm, the theory of track processing and the unsensitive Kalman filter UKF algorithm are introduced. On this basis, a data processing scheme based on clustering is proposed. The feasibility of the scheme is verified by simulation data. 2. The C / C real-time implementation of external emitter radar data processing algorithm is studied. With the help of open source matrix library Armadillo, which has excellent performance and ease of use, the corresponding data processing algorithm is transferred smoothly from Matlab code to C / C code. According to the characteristics of some commonly used linear data structures, various data structures are selected and determined. On this basis, the real-time implementation of the established algorithm is carried out, and the real-time performance of the program is verified by processing the multi-frequency data. The development of radar display and control terminal and the display of track are studied. According to the practical engineering needs, this paper puts forward the realization scheme of radar display and control terminal based on Microsoft basic Class Library (MFCs), realizes the flexible user interaction function through menu options of different groups, and gives a method of ADS-B civil aviation track analysis and extraction. Design and implement the playback track structure, and finally use the software timer drive mode to display the track playback. 4. The data transmission between multiple radars is studied. The application of multi-sensor information fusion technology to multi-external emitter radar system is an effective measure to further improve its localization performance. Before this, the problem of multi-station data transmission needs to be solved first. In view of this, a data transmission scheme based on 3G wireless network is proposed. The practicability of the transmission is verified by the data transmission test, which lays the foundation for the next networking detection based on multi-radar data fusion.
