现有各类子空间DOA测向算法为避免阵列模糊一般要求阵元间距小于半波长,但为获得更好的测向性能又需要较大的阵列尺寸,这需要大量的阵元,提高系统复杂度和成本.为克服这个问题,本文基于多重信号分类(MUSIC)算法提出一种采用半径不同的多口径组合阵列进行DOA测向方法.其中小尺寸阵列能够避免测向模糊问题,同时对空间谱起到平滑作用,从而降低空间谱计算复杂度;而具有较少阵元数目的大尺寸阵列主要用于提高测向算法精度和分辨力.本文给出算法的原理与实现步骤,并对算法精度和分辨力进行了分析和仿真,理论分析和仿真结果表明算法的有效性.

由于项目需要用到cesium的飞行漫游功能，但是找遍了网络也没找到合适的，没办法，自己动手丰衣足食。在例子中实现了可以自己添加漫游的经纬度，自主定义每两个点之间的飞行高度和飞行时间，另外可以在两个地点的方向转换，实现了原地转换，放置了直接切换相机视角的突然感觉

Classical and Modern Direction-of-Arrival Estimation

Advances in Direction-of-Arrival Estimation pdf高清 English 2005 Book Description Because the direction to targets is usually expressed by the direction of arrival (DOA) of transmitted signals, determining the direction of arrival (DOA) of any signal is of critical importance to electrical engineers working on both civilian and tactical applications in radar and communications. This cutting-edge resource presents the latest developments in DOA estimation from the leading researchers in the field. The first compiled book in the field, this in-depth reference covers a wide range of key topics, from DOA estimation methods and source localization problems, to specific applications of DOA estimation and experimental setup and results. Practitioners discover how DOA estimation is one of the main functional requirements for direction-finding smart antennas in next generation mobile and stealth communication systems. The book also serves as an excellent text for graduate students and researchers studying in this area. 关于DOA估计、波束形成方面的书 本人费好大劲才从“国防科技论坛上”下载的，辛苦啊！物有所值
