angle of arrival (aoa) meaning in Chinese
到达角
Examples
- Based on the facts that time of arrival ( toa ) of the first multipath signal is always most close to that of los propagation and angle of arrival ( aoa ) of the first multipath signal is not always most close to that of los propagation among all multipath signals in nlos propagation environment , a location algorithm is proposed to mitigate the influence of nlos propagation , which effectively reduces the feasible region of a ms in macrocells
依据在非视距传播环境下存在的以下两个事实：第一，最先到达多径信号的波达时间总是最接近直达波的波达时间。第二，最先到达多径信号的波达方向并不一定最接近直达波方向。针对宏蜂窝系统，从有效减小移动台可行域的角度，提出了一种减轻非视距影响的定位算法。 - The emitter location methods commonly include : angle of arrival ( aoa ) measurement , time - difference - of - arrival ( tdoa ) measurement and aoa together with tdoa measurement . this paper derive some important techniques and theories bearing upon passive location in this field . three kinds of passive location algorithm in three - dimensional ( 3 - d ) space are deduced based on that of 2 - d space . at the same time each performance is analyzed , each graph of geometric dilution of precession ( gdop ) is emulated for different station position , different measurement error , and different target height . accordingly some valuable academic and emulational results are obtained by myself , which will provide researches in this field with definite technical refrence . at the end of this paper , the passive location method of jtids ( joint tactical distribution systems ) is discussed , which is expected to enforce the tactical performance of jtids in the intending development
本文汲取了该领域有关被动定位的重要技术和理论，在二维平面无源定位算法的基础上推导出了三维空间内的三种无源定位算法，并对各自的定位性能进行了理论分析和计算机仿真，模拟出不同的布站、不同的测量误差以及不同辐射源高度的情况下，三种定位方法各自对应的定位精度（ gdop ）分布图，同时对各自的定位性能进行了改进处理，得出了一些有价值的理论和仿真实验结果，这些结论可为今后在此领域的研究提供一定的技术参考。
