Abstract
Method of locating one or more transmitters on the basis of an array of sensors moving with respect to the transmitters comprising at least the following steps: determining the direction vectors a.sub.k corresponding to the response of the array of sensors to a source with incidence (.theta., .DELTA.) as a function of the incidence parameters .theta., .DELTA., and of the parameter .rho. related to the distortion of the phases on the sensors, transforming this vector a.sub.k so as to eliminate the unknown parameter .rho., into a vector c.sub.km, c'.sub.km, using the transformed vector to obtain the position of the transmitter using a maximized locating criterion.
