【摘要】：在通信基地或艦載通信平臺(tái)現(xiàn)有設(shè)備的基礎(chǔ)上,利用多付獨(dú)立工作的天線,構(gòu)成一個(gè)分布式陣列天線系統(tǒng)。在此天線系統(tǒng)上,介紹了數(shù)字定向發(fā)射波束形成的原理,分析了實(shí)際發(fā)射過(guò)程中的存在的各種誤差,及其對(duì)波束合成的影響,并提出采用校準(zhǔn)的方法以降低這些誤差對(duì)發(fā)射波束合成的影響。以不規(guī)則圓陣布陣為例進(jìn)行仿真,結(jié)果表明數(shù)字定向發(fā)射系統(tǒng)可以有效地實(shí)現(xiàn)對(duì)某一定點(diǎn)目標(biāo)方向的功率增強(qiáng)。系統(tǒng)可以在線實(shí)時(shí)調(diào)整相位參數(shù),能夠分時(shí)實(shí)現(xiàn)對(duì)某一段方向的掃描發(fā)射或者多點(diǎn)定向發(fā)射。
[Abstract]:Based on the existing equipment of communication base or shipborne communication platform, a distributed array antenna system is constructed by using multiple independent antennas. In this antenna system, the principle of digital directional beamforming is introduced, and various errors in the actual transmission process are analyzed, as well as its influence on beamforming. A calibration method is proposed to reduce the effect of these errors on beam synthesis. Taking irregular circular array as an example, the simulation results show that the digital directional transmission system can effectively realize the power enhancement of a fixed target direction. The system can adjust the phase parameters in real time and realize the scanning or multi-point directional emission in a certain direction in time sharing.
