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。
By using the generalized function in the linear array synthesis the direction diagram with approximate flat top in wide Angle region and with or without a single side lobe can be obtained.
将广义函数用于线天线阵综合,可得到广角近似平顶的方向图,亦可得到具有单一付瓣和无付瓣的方向图。
The increase of lobe diffusion angle results in the increase of velocity circulation at the lobe exit section, but it raises the mixing loss and lowers the pressure recovery coefficient.
扩张角的增加可提高速度环量,但是流动混合损失增加,总压恢复系数减小。
The results show that the cord Angle and cord plies are important factors that affect the vertical characteristic of rolling lobe air springs.
结果表明,帘线角和帘线层数是影响膜式空气弹簧垂向特性的重要因素。
It has the characteristics of the small volume, light weight, high aperture efficiency and low wide-angle minor lobe and so on.
它具有体积小、重量轻、口径效率高、宽角副瓣低等特点。
