摘要
为了实现对相控阵雷达更加有效的侦察截获,必须对相控阵雷达波束及其扫描特征进行深入分析.通过描述相控阵雷达天线方位向与俯仰向的加权方式,仿真得到了相控阵雷达的方向图;根据此信息,结合不同工作模式下相控阵雷达天线扫描情况,建立侦察截获模型,仿真得到了侦察系统接收到信号的幅度变化图;并对相控阵雷达波束扫描时侦察系统截获概率进行了较深入分析,得到了一些有益的结论.
For realizing the more effective reconnaissance and interception to the phased-array radar,the phased-array radar beams and its scanning features have to be deeply analyzed.By representing the antenna azimuth and pitching direction＇s weighted mode of the phased-array radar,this paper obtains the patterns of the phased-array radar through simulation,based on which,the reconnaissance and interception model is set up by combining the scanning case of radar antenna under various operating modes,the amplitude variation chart of the signals received by the reconnaissance system is also obtained through simulation,the interception probability of the reconnaissance system while the radar beams scanning are analyzed more deeply,and some significant conclusions are drawn as well in this paper.
