浅谈同步卫星天线的调整

Adjustment of syn-chronous satellite aerial

调整卫星天线首先必须知道预收卫星的经、纬度和接收地的经、纬度,通过简单的计算后,再从计算曲线中查出方位角、仰角、极化角及天线噪声温度的具体数据,卫星天线再根据这些数据进行定位,然后接入系统中进行微调,微调时经过几次反复后,即得到满意的收视(听)效果。

In order to adjust satellite aerial, first of all, the longitudes and latitudes of the satellite and the receiving station should be understood respectively. After simple calculating, specific data of position angle, elevation angle, polarization angle and antenna temperature from the calculating curve will be found out. Satellite aerial will fix the position according to the data, then it will be connected to the receiving equipment to begin fine tuning. After several times of fine tunings; a satisfying receiving result can be got finally.
