摘要
相控阵天线目前广泛应用于雷达中,促进了多目标、多任务雷达的发展。但随着电扫描角度的变化,其诸多指标也随之变化,对雷达的性能产生直接影响,因而对相控阵天线方向图进行实时定量分析具有重要意义。文章基于相控阵天线的基本原理,利用LabVIEW语言开发了相控阵天线方向图仿真软件。软件设置了相控阵天线各影响参数的输入控件,通过图形和数值2种方式进行仿真结果的显示,并以表格文件存储。通过不同条件下的仿真结果对比分析,软件可合理有效地对相控阵天线方向图进行实时定量的仿真分析,可应用于相控阵雷达的性能分析和评估中。
Phased array antenna is widely used in radar, which promotes the development of multi-target and multi-task radar. However, with the change of electric scanning angle, many of its indicators also change, which impacts on the perfor. mance of radar directly. Therefore, it is great significance to make real-time quantitative analysis of phased array antenna. Based on the basic principle of phased array antenna, the simulation software of phased array antenna pattern was devel. oped by using LabVIEW language. The software sets the input controls of the parameters of phased array antenna, displays the simulation results by graphics and numerical methods, and stores them in tables and files. Through comparative analy. sis of simulation results under different conditions, the software can reasonably and effectively simulate and analyze phased array antenna patternin in real time and quantitatively, and can be applied to performance analysis and evaluation of phased array radar.
