NLOS GPS signal detection using a dual-polarisation antenna [PDF]

, 2012
The reception of indirect signals, either in the form of non-line-of-sight (NLOS) reception or multipath interference, is a major cause of GNSS position errors in urban environments.

Localization of Agricultural Mobile Robot Based on Two UWB Tags and Heading Angle L2IB System

Agriculture
The dense tree canopy in the complex orchard environment obstructs wireless positioning signals and generates NLOS interference, which reduces the positioning accuracy of agricultural mobile robots.

Precise Reconstruction Method for Hidden Targets Based on Non-line-of-sight Radar 3D Imaging

Leida xuebao
Non-Line-Of-Sight (NLOS) 3D imaging radar is an emerging technology that utilizes multipath scattering echoes to detect hidden targets. However, this technology faces challenges such as the separation of multipath echoes, reduction of aperture occlusion,

Virtual reference device-based NLOS localization in multipath environment

, 2014
This letter presents a novel non-line-of-sight (NLOS) localization scheme based on the concept of virtual reference device. The position of virtual reference device for each NLOS path can be determined if the initial mobile device position can be ...

Sensing in NLOS: a Stroboscopic Approach [PDF]

Sensing in non-line-of-sight (NLOS) is a well-known issue that limits the effective range of radar-like sensors. Existing approaches for NLOS sensing consider the usage of either metallic mirrors, that only work under specular reflection, or dynamically ...

Received signal strength characterization in mixed LOS and NLOS environments

The received signal strength (RSS) measurement is widely adopted in wireless positioning due to its simplicity and accessibility. This article utilizes the Boolean line model (BLM) to characterize the RSS distribution considering both line-of-sight (LOS)
