随着电视信号的减弱,要求所用的接收天线具有更高的增益。但在存在强力电视台对欲接收的弱电视信号干扰的情况下,单纯提高接收天线的增益往往並不能解决问题。本文在用谢昆诺夫圆对阵列进行分析及综合的基础上,提出了一种既能保持主接收方向不变並确保天线在该方向上的增益性能、又能改变天线的波束零点使之对准干扰方向从而进行有效地抑制的阵列。
As the television signal is weakened, the receiving antenna used is required to have a higher gain. However, in the presence of strong television stations to receive weak signal interference, simply by increasing the receive antenna gain often does not solve the problem. In this paper, based on the analysis and synthesis of Shektinov circle array, this paper proposes a method that can not only keep the main receiving direction unchanged but also ensure the gain performance of the antenna in this direction, but also change the zero point of the antenna beam Targeting the direction of interference to effectively suppress the array.
