摘要
针对双极化阵列工程实现难度大、成本高的问题,提出一种基于分时双极化阵列自适应波束形成(ADBF)处理方法.首先完成阵面接收信号的子阵级合成,分别计算水平极化和垂直极化两类子阵的导向矢量,进行自适应处理;然后从两个极化处理通道中选取信干噪比(SINR)较大者输出.仿真结果表明,该方法能够在大多数场景下实现干扰的有效抑制,具有较强的适用性和稳健性.该方法处理简单、易于工程实现,有效解决了子阵合成前数据量大、目标极化参数无法实时获取等问题.
In response to the difficulty and high cost of implementing dual-polarized array engineering,this paper proposes an adaptive digital beamforming(ADBF)processing method based on time division dual-polarized array.Firstly,the sub-array level synthesis of the received signal is completed;the guiding vectors of the horizontally and vertically polarized sub-arrays are calculated respectively,and the adaptive processing is carried out.And then,from the two polarization processing channels,the one with larger signal to interference plus noise ratio(SINR)is selected for output.Simulation results show that the proposed method can effectively suppress interference in most scenarios,and has strong applicability and robustness.This method is simple to process and easy to implement in engineering,and effectively solves the problems such as large amount of data before the synthesis of sub-array and the failure to obtain the target polarization parameters in real time.
