Non-line-of-sight propagation - Wikipedia
网页Non-line-of-sight (NLOS) radio propagation occurs outside of the typical line-of-sight (LOS) between the transmitter and receiver, such as in ground reflections. Near-line-of-sight (also NLOS) conditions refer to partial obstruction by a physical object present in the innermost Fresnel zone.
非视距 - 百度百科
网页我们通常将无线通信系统的传播条件分成 视距 (LOS)和非视距 (NLOS)两种环境。. 视距条件下，无线信号无遮挡地在发信端与接收端之间”直线“传播，这要求在第一菲涅尔区 (First Fresnel zone)内没有对无线电波造成遮挡的物体，如果条件不满足，信号强度就会明显 ...

网页2024年9月21日 — Non-line-of-sight (NLOS) imaging, recovering the hidden volume from indirect reflections, has attracted increasing attention due to its potential applications. Despite promising results, existing NLOS reconstruction approaches are constrained by the reliance on empirical physical priors, e.g., single fixed path compensation. Moreover, these approaches still possess limited generalization ...
