中文摘要:

根据布郎的参数,大耳朵的蝙蝠是翼,由线和飞机做了的一个简单倾斜地截断的蝙蝠耳朵模型被设计,它数字地与有限元素方法被模仿。当频率增加了,远地的择向性的变化在举起和方位角被分析。结果显示出那,与布朗的翼相比大耳朵的蝙蝠,现在的模型在在方位角的扫描、更好的择向性和更大的角度在 elevation.In 增加放大的驾驶的频率的更宽的带宽有优点,基于单个底,车站能被使用驾驶的频率扫描天线完成的一个无线的放方法。

英文摘要:

According to the parameters of a Brown Big-eared bat's pinna,a simple obliquely truncated bat ear model that made by line and plane was designed,which was numerically simulated with finite element method.The change of far-field directivity was analyzed in elevation and azimuth as the frequency increased.The results show that,compared with the pinna of the Brown big-eared bat,the present model has the advantages in wider bandwidth of frequency driven scanning,better directivity in azimuth and larger angle scales in elevation. In addition,a wireless positioning method based on single base station could be achieved by using a frequency driven scanning antenna.
