array gain中文什么意思
例句與用法
- A broadband high array gain beamforming scheme is developed , based on the narrowband optimal array gain processing procedure
基于小間隔透聲圓陣的窄帶最佳陣增益處理，提出了一種寬帶高增益波束形成方案。 - Lake - experiment for an un - baffled practical circular array verified the effectiveness and error tolerance of this new method . 5 . the intrinsic mechanism of optimal array gains is studied for the scenario when the element spacing is less than one half - wavelength , with emphasis on un - baffled circular arrays
針對(duì)一個(gè)24元均勻分布圓陣的湖上實(shí)驗(yàn)結(jié)果表明，這種新的恒定束寬波束形成方法是有效的，且在一般條件下，對(duì)基陣陣元幅度和相位響應(yīng)誤差具有良好的寬容性。 - Modern sonar systems generally use hydrophone arrays and advanced signal processing techniques to improve their detection and localization abilities , whereas beamforming plays an important role . as it is known , the conventional beamforming approach provides limited array gains and low interference suppression abilities , and cannot resolve multi - targets distributed within a small spatial region
但是，傳統(tǒng)的波束形成方式所提供的陣增益有限，對(duì)干擾的抑制能力不強(qiáng)，且不能分辨空間小角域內(nèi)的多個(gè)目標(biāo)，影響了聲吶系統(tǒng)整體性能的發(fā)揮。 - The characters of this antenna lie in three points : using yagi - uda antenna to obtain antenna gain through the radial direction ; making full use of the space of the base station along the z - axis direction to get array gain ; arranging the antenna array properly to achieve pattern diversity in azimuth plane
其特點(diǎn)集中體現(xiàn)在三個(gè)方面:在天線(xiàn)徑向通過(guò)八木天線(xiàn)的形式獲得增益;充分利用基站空間在z向組成陣列獲取陣列增益;利用開(kāi)關(guān)八木天線(xiàn)方向圖可重構(gòu)的特性,通過(guò)合理的布局,在方位面內(nèi)實(shí)現(xiàn)角度分集。
百科釋義
In MIMO communication systems, array gain means a power gain of transmitted signals that is achieved by using multiple-antennas at transmitter and/or receiver, with respect to single-input single-output case. It can be simply called power gain.
