Wahab Khawaja et al.
This paper studies the air-to-ground ultra-wideband channel through propagation measurements between 3.1 GHz to 4.8 GHz using unmanned-aerial-vehicles (UAVs). Different line-of-sight (LOS) and obstructed-LOS scenarios and two antenna orient...
Omnidirectional Optical Crosslinks for CubeSats: Transmitter Optimization [0.03%]

CubeSat swarm in LEO orbit is an attractive alternative to present-day expensive and bulky satellite-based remote sensing systems. This paper presents the design and optimization rules to achieve omnidirectional, high speed, long-range (mor...
Kalman Filter-based Robust Closed-loop Carrier Tracking of Airborne GNSS Radio-Occultation Signals [0.03%]
基于卡尔曼滤波的机载GNSS无线电掩星信号鲁棒闭环载波跟踪方法研究

GNSS radio occultation (RO) signals have been demonstrated as a viable means to retrieve atmospheric profiles. Current GNSS-RO observations rely on open-loop (OL) processing of the signals, especially for signals propagating through the low...
Hankel Matrix Rank as Indicator of Ghost in Bearing-only Tracking [0.03%]
利用 Hankel矩阵秩作为 bearings-only跟踪中的幽灵目标判据
