摘要
相对于常规的告警比幅测向系统,三维告警不仅要测量目标的方位角,还需要测量目标的俯仰角,其比幅天线布局不同。通过对比计算三维告警和常规两维告警覆盖的立体角,从理论上分析了两种条件下比幅测向天线数量的区别。并在此基础上,提出了一种三维告警测角系统天线的布局方式,并说明了这种布局方式的优点。
The 3D warning system is different from the conventional warning system. It has to measure the elevation angle and the azimuth, so the deployment of their antennas is different. The solid angles of the two kinds are calculated and compared, the differences in DF antenna numbers and deployment are analyzed theoretically. Then a particular DF antennas distribution is put forward, and the excellence of the way is shown.
