摘要
要使车载接收天线能够正常接收到发射的信号,天线的方位角和仰角的准确定位至关重要。车载天线的方位角和仰角可以根据公式在安装调试天线以前计算出来,但是,由于车载接收天线的大小不同,结构各异,定位一副实际天线的方位角和仰角是一件困难的事情。文中介绍的方位角和仰角的定位方法使用简单、有效,适用于多种结构的车载接收天线。
To make vehicle receiving antenna receive radiated signals optimally, the crwx is pointing its azimuth and elevation exactly. Its azimuth and elevation could be calculated by formula before installation. However, due to the difference of size and structure of vehicle receiving antennas, it is difficult to measure and orient azimuth and elevation exactly in practice. In this paper orienting methods of azimuth and elevation are introduced, they are simple and effective, could be applicable to various structures of vehicle receiving antenna.
