一种简化的雷达三维探测数据生成方法研究

Study on a Simple Method for Generating 3D Radar Detecting Data

雷达电子战三维实时视景仿真能够全面表现雷达电子战系统的作战态势、进程和对抗效果,为指挥员正确把握战场态势提供支持。在进行雷达电子战三维视景仿真时,传统的方法是直接构建雷达的三维探测数据,然后生成三维态势图。传统方法导致计算复杂,数据量大,不能够满足实时仿真的要求。现提出了一种在雷达探测范围二维包络线计算模型的基础上,结合垂直面上雷达天线方向图,空间数据生成的简化算法,同时考虑了雷达受到干扰情况下雷达天线垂直方向函数的修正方法。以上方法简化了计算过程,有效的减少了数据量。利用提出的方法,开发的视景仿真系统在实践中得到了应用,能够满足实时要求,文中给出了具体实例和仿真结果图。

Using Radar - EW Three - dimensional real - time visual simulation method, the situation, process and effects of Radar - EW can be expressed comprehensively. It can provide support to command for gaining the situation of battlefield. Traditional method creates detecting data of radar directly and generating three - dimensional situation chart. Because of complex calculation and mass data, this method can not meet the need of real - time simulation. The paper introduces the three - dimensional data generating method based on the Planar Radar Detecting Area calculating method and vertical detecting distance calculating method. This method takes the adjustment of direction function into account and predigests the process of calculation. It reduces the quantity of data effectively. This method has been used in the development of visual simulation system. It meets the need of real - time. At last the paper gives the example and the chart of result.
