单词	grating lobe
释义	grating lobe 简明释义光栅瓣：在离散孔径天线（如相控阵）中，元件间距大于半个波长，空间混叠效应使得从期望方向以外的可见角度入射到阵列的平面波能够相干叠加，导致产生光栅瓣。光栅瓣是不期望的，且与主瓣相同。光栅瓣的感知差异是由于非各向同性天线元件的辐射图案不同程度地影响主瓣和光栅瓣。对于各向同性天线元件，主瓣和光栅瓣是相同的。网络释义 1 ?光栅波瓣 ... lobe 波瓣 ; 波瓣、凸出部分 ; 边波瓣 ; 主波瓣 grating lobe 光栅波瓣 lobe abstraction 波瓣成形 ... 2 ?光栅瓣 ... 光栅“伴线” grating satellite; 光栅瓣 grating lobe; 光栅比 grid ratio; ... 3 ?光栅划线 ... 光栅效率 grating interferometer 光栅划线 grating lobe 光栅波瓣 grating monochromator ... 短语 1 Grating lobe pattern 栅瓣图 2 grating lobe suppression 栅瓣抑制 3 grating lobe series 栅瓣级数双语例句 1 Thus, the scan angle is increased and the grating lobe phenomenon is reduced. 因此，扫描角会增加同时栅瓣现象会减少。 2 This paper analyses the pattern function of DBF in subarray.
