常見例句A steering-invariant constant beamwidth beamforming algorithm is proposed. 該文提出了方向不變恒定束寬波束形成算法。Currently there are two typical spot-beam models with equal beamwidth and equal spotarea. 目前等波束寬度模型和等點波束面積模型是兩種常用的點波束模型。A nesting line array can maintain the constant beamwidth over a very wide frequency range (N octaves, N = 7). 摘要線性嵌套陣可以很好地在很寬的頻率(N個倍頻程,N=7)上實現(xiàn)恒定束寬。The effect of antenna parameters on the beamwidth and side lobe level is analyzed. 分析了天線參數(shù)對主瓣寬度和副瓣電平的影響;With the aid of a computer, curves of beamwidth and side lobe versus the antenna parameters are plotted. 并借助計算機繪出了主瓣寬度和副瓣電平與天線主要參數(shù)的關(guān)系曲線;Wideband beamforming with constant beamwidth is one of the key problems in array signal processing. 寬帶恒定束寬波束形成器是基陣信號處理中的難點。 返回 beamwidth
