【摘要】：提出一种适用于平面天线阵列的微波和数字处理的联合结构及相应的处理算法.这种结构能够以全数字方式估计波达方向,并能以两种方式进行波束形成.一种是全数字处理方式,另一种是按照阵列单元布局的矩阵处理;用数字微波移相器在俯仰面将天线单元的接收微波信号合成微波波束;采用数字波束形成方式形成最终的波束.并提出了双线法估计波达方向的技术.仿真和测试表明其灵活性和可行性.
[Abstract]:This paper presents a joint structure and corresponding processing algorithm for microwave and digital processing of planar antenna arrays, which can estimate the DOA in a full digital manner. Beamforming can be carried out in two ways: one is all-digital processing mode, the other is matrix processing according to array unit layout, and the received microwave signal of antenna unit is synthesized by digital microwave phase shifter on pitch plane, and the received microwave signal of antenna unit is synthesized by digital microwave phase shifter. The final beam is formed by digital beamforming, and a two-wire method is proposed to estimate the DOA. The simulation and test results show that it is flexible and feasible.
