A project of time division single channel adaptive antenna

提出了自适应天线系统的一种时分单通道接收机方案,针对HF三元阵列自适应零位天线系统,分析了其帧结构、采样周期、时隙及其与载波之间的关系。给出了直接利用采样数据计算相关矩阵的算法。解决了多通道接收机电路复杂,难以保证各通道性能一致的问题。模拟测试结果证明了该方案可对两个任意来向的干扰进行有效的抑制。

This paper presents a time-division single channel receiver scheme of adaptive antenna system. Sampling period, frame structure, time-slot and the relationships with the carrier are analyzed for the three-array HF adapti ve nulling antenna system. The algorithm of correlation matrix using the sample datum directly is given. So the complicacy and consistency of the multi-channel receiver circuit is avoided. The measurement results show that the scheme can suppress interference from any one or two directions efficiently.
