Global navigation satellite systems (GNSS) like GPS but also Galileo, GLONASS, and
Beidou represent an important infrastructure to our society. They provide position and timing …

Critical government and industry sectors (such as law enforcement, transportation,
communication, and finance) are growing increasingly dependent on Global Navigation …

This paper presents a precorrelation interference detection method based on statistical
analysis in the time-frequency (TF) domain for global navigation satellite system signals. In …

Undesired interfering signals are considered to be one of the main threats to the correct
behavior of new Global Navigation Satellite System (GNSS) receivers. There is a huge …

This work investigatesradio frequency interference (RFI) effect on LEO satellite-based GNSS-
Reflectometry (GNSS-R) data and presents RFI detection and mitigation results. Specifically …

Micro-Doppler signatures from four CAD aircraft engine models and one experimental
engine model are analyzed using joint time-frequency analysis (JTFA). The signatures are …

Unmanned Aerial Vehicles (UAVs) rely heavily on Global Navigation Satellite Systems
(GNSS) for positioning and navigation when performing tasks. At the same time, low-cost …

As wireless communication applications require more and more bandwidth, the demand for
wideband antennas increases as well. One of the most applicable frequency bands is X …

A class of linear derivative constraints, which provides robustness to the conventional
narrowband uniform linear array configuration so as to handle broadband and moving …

In this paper, we provide an analysis of radio frequency interference for global navigation
satellite system reflectometry (GNSS-R) using multi-frequency global positioning system …
