A signal phasor's amplitude in the presence of noise will follow a Rician distribution.
For strong signals, this approximates a gaussian distribution, while for weak signals, this approaches a Rayleigh distribution.

\chapter{Synchronising Detectors with a Beacon Signal}
\label{sec:disciplining}
The detection of extensive air showers uses detectors distributed over large areas. %<<<
Solutions for precise timing ($< 0.1\ns$) over large distances exist for cabled setups, e.g.~White~Rabbit~\cite{Serrano:2009wrp}.
Solutions for precise timing ($< 0.1\ns$) over large distances exist.
Initially developed for fibre-optic setups, White~Rabbit~\cite{Serrano:2009wrp} is also being investigated to be used as a direct wireless time dissemination system~\cite{Gilligan:WR-over-mm-wave}.
\\
However, the combination of large distances and the number of detectors make it prohibitively expensive to realise such a setup for \gls{UHECR} detection.
For this reason, the time synchronisation of these autonomous stations is typically performed with a \gls{GNSS} clock in each station.

Using radio antennas to detect \glspl{UHECR} has received much attention recently.
The \acrlong{Auger} is currently being upgraded to \gls{AugerPrime} incorporating radio detectors with scintillators and water-cherenkov detectors.
Other experiments, such as \gls{GRAND}, plan\Todo{word} to fully rely on radio detection only.
The \acrlong{Auger} is currently being upgraded to \gls{AugerPrime} incorporating radio and scintillation detectors together with the already existing water-Cherenkov and fluorescence detectors.
Other experiments, such as \gls{GRAND}, envision to rely only on radio measurements of an \gls{EAS}.

% Timing not enough
Time information in such large observatories is typically distributed using \glspl{GNSS}, reaching up to $10\ns$ accuracy under very good conditions.

In addition to a bandpass filter, more complex filter setups are used to remove unwanted components or introduce attenuation at specific frequencies.
For example, in \gls{GRAND}, the total frequency band ranges from $20\MHz$ to $200\MHz$
such that the FM broadcast band ($87.5\MHz \text{--} 108\MHz$) falls within this range.
such that the FM broadcasting band ($87.5\MHz \text{--} 108\MHz$) falls within this range.
Therefore, notch filters have been introduced to suppress signals in this band.
