  abstract = {{I}n the nearshore, describing the complex individual wave dynamics remains a key challenge. {I}n this paper we test the ability of the {R}adon {T}ransform to produce estimates of individual wave celerities and to separate incoming and outgoing waves conserving the temporal characteristics. {T}he {R}adon {T}ransform is a projection of a two-dimensional field into polar space. {O}blique features such as propagating crests in a spatio-temporal space are identified with density peaks in the polar space. {I}n this paper, the {R}adon {T}ransform is applied to synthetic test cases including a wide range of beach slopes and wave conditions. {T}he {R}adon {T}ransform shows good skills at estimating individual celerity and separating incoming and outgoing components with a relative {RMS} error lower than 10%, even a standing wave node. {T}he accuracy is fairly insensitive to wave characteristics whereas the main limitations rise from the sampling scheme and are the number and density of wave gauges. {T}he distance between gauges should be less than one third of the shortest wavelength, while the set of gauges should cover more than one third of the longest wavelength.},
