一种单通道自适应零位天线系统的研究与设计

在自适应阵列天线系统中,通常的多通道接收机电路复杂,难以保证各通道性能的一致性,以及使用的可靠性.文中对HF自适应三元阵列零位天线系统提出了一种单通道检测接收机方案,并分析了实现的可行性,给出了具体的实现方法,同时讨论了相关矩阵的算法.为了降低镜频干扰、交调和互调干扰,接收机采用了双中频方案.模拟测试结果证明了该方案的可行性.

Study and Design of a Single Channel Adaptive Nulling Antenna System

In the adaptive array antenna system, the ordinary multi-channel receiver circuit is very complicated, and it is difficult to assure the consistency of all channels and the reliability in application. This paper proposes a single channel detection receiver scheme for the HF adaptive three-array nulling antenna system and analyzes the feasibility of and the methods for its implementation. Also discussed is the algorithm for the correlation matrix. In order to decrease the mirror frequency interference, cross interference and inter-modulation interference, double IF (Intermediate Frequency) is adopted in the receiver. The measurement results of simulation show that the scheme proposed is feasible.
