Abstract
A method of detecting interference in a satellite radio-navigation signal, calculates an item of information representative of the slope of the correlation function correlating the said signal with a local spreading code. The correlation function has substantially the theoretical form of an isosceles triangle, with the slope being estimated on any one of the equal-length sides of the isosceles triangle. The method further includes comparing the item of information with a detection threshold configured at least as a function of a target signal-to-noise ratio.
