Claim:
A method for the verification of anti-jamming in a communications system having several sensors or adaptive antennas, comprising the following steps: estimating a mean power □^y of the output of the communications system, estimating a respective power values Pu or P′u, of a station u, the antenna noise Pa or P′a, the thermal noise PT, or P′T, estimating at least one of the following ratios: J tot ⁢ / ⁢ S tot = ⁢ ( ∑ P p = 1 ⁢ P p ) ⁢ / ⁢ ( ∑ U u = 1 ⁢ P u ) with ⁢ p = ⁢ the jamming unit = ⁢ sum ⁢ ⁢ ⁢ of ⁢ ⁢ the ⁢ ⁢ ⁢ power ⁢ ⁢ ⁢ values ⁢ ⁢ ⁢ of ⁢ ⁢ ⁢ the ⁢ ⁢ residual ⁢ ⁢ jamm ⁢ ing ⁢ units ⁢ / ⁢ sum ⁢ ⁢ of ⁢ ⁢ the ⁢ ⁢ power ⁢ ⁢ ⁢ values ⁢ ⁢ ⁢ of ⁢ ⁢ ⁢ the ⁢ ⁢ stations ⁢ ⁢ on ⁢ the ⁢ ⁢ reception ⁢ ⁢ band ⁢ ⁢ B J tot ⁢ / ⁢ S u = ⁢ ( ∑ P p = 1 ⁢ P p ) ⁢ / ⁢ P u = ⁢ sum of the power values of the residual jamming ⁢ units/power of the station ⁢ u ⁢ in the reception ⁢ band ⁢ B . J u / S u = ( ∑ p = 1 P ⁢ P pu ) / P u with Ppu=power of the jamming unit p in the reception band Bu| comparing at least one of the three ratios with a threshold value.
