【摘要】:提出一種適用于平面天線陣列的微波和數(shù)字處理的聯(lián)合結(jié)構(gòu)及相應(yīng)的處理算法.這種結(jié)構(gòu)能夠以全數(shù)字方式估計(jì)波達(dá)方向,并能以兩種方式進(jìn)行波束形成.一種是全數(shù)字處理方式,另一種是按照陣列單元布局的矩陣處理;用數(shù)字微波移相器在俯仰面將天線單元的接收微波信號(hào)合成微波波束;采用數(shù)字波束形成方式形成最終的波束.并提出了雙線法估計(jì)波達(dá)方向的技術(shù).仿真和測(cè)試表明其靈活性和可行性.
[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.
