【摘要】：随着现代战争的发展,战场环境的变化越来越复杂,这就对雷达系统的性能提出了越来越高的要求。同时雷达系统的设计变的越来越复杂,这就为雷达系统的调试带来了很大的困难。为了能在较短的时间内完成系统的调试、定型和批量生产,若采用外场检飞来对雷达系统进行调试,成本高,调试周期长,无法满足现在对雷达系统性能调试的需求;如果采用雷达信号模拟器对雷达系统进行调试,则可有效的缩短调试周期,降低实验成本。所以雷达模拟器已经成为雷达系统调试时不可或缺的重要设备。随着现代计算机技术、大规模数字集成电路技术和雷达技术等相关领域的迅猛发展,现在的雷达模拟器已经摒弃了单独采用硬件或者软件模拟的方法,现已广泛采用软、硬件相结合的形式,阵列雷达回波信号模拟器就是采用的此方法。而模拟器系统中的软件部分是操作者和雷达信号模拟器系统人机交互的一个平台,是控制模拟器有效工作的核心,并且可以通过雷达信号模拟软件模拟产生各种环境条件下的雷达回波信号,为雷达系统调试提供一个可靠的数据来源。所以,软件设计的好坏是雷达信号模拟器能否高效、快速工作的重要因素。本文主要以阵列雷达回波信号模拟器系统的研制为背景,详细阐述了阵列雷达信号模拟器系统整体硬件和软件的设计方案以及各部分要完成的功能,并对设计方案中的各部分功能进行了详细说明。在此基础上,给出了雷达信号模拟器整体的数据流向和上位机界面应用程序的设计流程,对系统上位机软件的功能实现做了详细的说明,并给出了调试问题的解决方法。最后,详细说明了雷达回波信号的生成方法,主要是通过设置雷达信号模拟软件中相应的参数,产生需要的多种雷达回波信号。由于该软件只能产生单阵元的雷达信号,所以,为了实现40阵元的回波信号,文中以104?和85?平面阵为例,说明了波束形成的基本概念,以及各个阵元导向矢量的计算方法,给出了104?和85?平面阵的方向图仿真结果,并对其做了简单分析。在此基础上完成了整个系统软件的设计和信号的产生,实现了系统各个部分的功能。
[Abstract]:With the development of modern warfare, the change of battlefield environment is becoming more and more complicated, which puts forward more and more requirements for the performance of radar system. At the same time, the design of radar system becomes more and more complicated, which brings great difficulties to the debugging of radar system. In order to complete the system debugging, setting and batch production in a short time, if the radar system is debugged by field inspection, the cost is high, the debugging period is long, and it can not meet the needs of the radar system performance debugging. If the radar signal simulator is used to debug the radar system, the debugging period can be shortened and the experiment cost can be reduced. Therefore, radar simulator has become an indispensable and important equipment in the debugging of radar system. With the rapid development of modern computer technology, large-scale digital integrated circuit technology, radar technology and other related fields, the current radar simulator has abandoned the use of hardware or software alone, and has been widely used in software. This method is adopted by array radar echo signal simulator in the form of hardware combination. The software part of the simulator system is a platform for man-machine interaction between the operator and the radar signal simulator system, which is the core of the effective work of the control simulator. The radar echo signal can be generated by the simulation software of radar signal under various environmental conditions, which provides a reliable data source for the debugging of radar system. Therefore, the quality of software design is an important factor for the high efficiency and fast operation of radar signal simulator. Based on the research and development of array radar echo signal simulator system, the whole hardware and software of array radar signal simulator system and the functions of each part are described in detail in this paper. The functions of each part of the design are explained in detail. On this basis, the design flow of the whole data flow direction and the upper computer interface application program of the radar signal simulator is given, the function realization of the upper computer software of the system is explained in detail, and the solution to the debugging problem is given. Finally, the generating method of radar echo signal is explained in detail, mainly by setting the corresponding parameters in radar signal simulation software to generate various radar echo signals needed. Because the software can only produce radar signal of single array element, so, in order to realize the echo signal of 40 array elements, in this paper, 104? And 85? The basic concept of beamforming and the calculation method of the guiding vectors of each element are illustrated for an example of plane array. And 85? The simulation results of the pattern of plane array are analyzed briefly. On this basis, the design of the whole system software and the signal generation are completed, and the functions of each part of the system are realized.
