这一直射路径通常被称为视距传播(LOS Path of Propagation)。 影响视距通信(LOS Communication)的因素 反射障碍物(Reflective Obstacles) 从接收天线的角度来看,沿视距传播的电磁波包含大部分的接收信号,但沿间接路径(Indirect Path)传播的波前也可以到达接收天线。传播路径上的物理元素,如建筑,金属结构甚至地貌(水面)...
微振动分析主要关注光学设备的LOS,分析干扰源对仪器性能的影响。通常来说,需要仪器的详细模型,以便考虑到仪器和航天器之间的模态耦合。如果预期的仪器结构模态高于感兴趣的频率范围,即可使用简化模型。 主要关注成像面位置作为微振动评估准确性,以LOS作为评价指标,以确定光学件(反射镜、透镜、焦平面)与整体仪器性能之间关...
channels expected from the first reference signal and the second reference signal when transmitted along the LOS path between the transmitter and the wireless device, and determines which path (if any) of the multi-path channels corresponds to the LOS path between the transmitter and the wireless ...
Line of sight is the direct path between two points. It's called the "line of sight" because if a person was standing at one point, the LOS would be the path they look along. If an object were blocking the view, it would be considered out of sight or an obstructed line of sight....
unity下的Line of Sight(LOS)的绘制 先说说什么是Linf of Sight。在很多RTS游戏中,单位与单位之间的视野关系经常会受到障碍物遮挡。Line of Sight指的就是两个物体之间是否没有障碍物遮挡。 比如在dota中,玩家的视野会被树挡住。此时树后面的区域对该玩家是不可见的。

This paper presents an overview of the Line-of-Sight (LOS) guidance law, which is a widely used method for generating heading reference trajectories, for path-following applications of marine vehicles. Due to the fact that these reference trajectories depend also on the form of the path, five...

underlying both methods is an assumption that the signal is mainly propagating along a direct line-of-sight (LOS) path, which is unlikely in most practical RFID setups [42, 18]. Signals bounce off various reflectors in the environment, and multiple reflected copies combine at a wireless...
Then, a line-of-sight (LOS) guidance law based on BGF is designed to follow the desired path accurately in the presence of ocean disturbances, in which the parameter estimation and the tracking errors are both proven to be bounded. Furthermore, the closed-loop cascade BGF-LOS guidance ...
