Abstract: Method and device for detecting a target spectrum and its frequency location in a scenario contaminated with strong jammers on other interferers. The detection is based on the geodesic distance between the correlation matrix (RD) of the received signal and the correlation matrix (RT) of the target spectrum (TS) which is assumed known in shape and bandwidth. The detection happens when the threshold (Formula (I)) is overcome. The frequency location is based on the minimization of the mean square error between RD and RT.
