Conflict Resolution Strategy Based on Flight Conflict Network Optimal Dominating Set

open access: yesInternational Journal of Aerospace Engineering, 2022
Aiming at the problem that the air traffic flow is increasing year by year and the flight conflicts are difficult to be deployed, we take aircraft as the node and established a flight conflict network based on the flight conflict relationship between ...

Research on BeiDou anti-spoofing technology based on comprehensive radio determination satellite service

open access: yesSatellite Navigation, 2020
The BeiDou system (BDS) plays a significant role in people’s lives, but its security is easily affected by spoofing attacks. The radio determination satellite service (RDSS) is a special service of BDS that provides two-way communication, positioning ...

BOC Signal Acquisition Algorithm Based on Similar Enfoldment

open access: yesInternational Journal of Aerospace Engineering, 2020
A BOC signal has been widely used in the Global Navigation Satellite System (GNSS). Although the BOC signal has many advantages, the autocorrelation function (ACF) of the BOC signal has lots of peaks, which makes signal acquisition difficult.

Hippocampus and retrosplenial cortex combine path integration signals for successful navigation [PDF]

open access: yes, 2013
The current study used fMRI in humans to examine goal-directed navigation in an open field environment. We designed a task that required participants to encode survey-level spatial information and subsequently navigate to a goal location in either first ...

A novel detection of radio-frequency signal based on an electro-opto-mechanical converter

open access: yesResults in Physics, 2022
We study a novel detection of radio frequency signal, which is realized by the coherent microwave-optical conversion and optical processing. An electro-opto-mechanical converter, which enables the bidirectional transduction of the information between ...
