The disclosure relates to the deployment and maintenance of a belt of autonomous sensors fitted out with warning sensors to monitor the area surrounding one or more sensitive points. It relates especially to anti-missile and anti-aircraft warning systems for naval surface ships against missiles and aircraft flying at low and very low altitudes. It consists in controlling the paths of the drones solely by means of their radius of curvature for which they receive an instructed value from the reference point or points. This instructed value is encoded by a frequency of a radioelectric signal sensitive to the Doppler effect. A modification of this instructed value of radius of curvature as a function of the signal of a proximity sensor makes it possible to avoid all problems of collision and to keep the drones at equal distance from one another. This mode of control proves to be particularly efficient and, at the same time, very simple.

[ What is claimed is:] [1.] A method for controlling flight paths of a plurality of drones, each of said plurality of drones being in flight about at least one radio-control transmitter and each comprising a transmitter and a receiver, said method comprising the steps of:transmitting a control signal from respective of the at least one radio-control transmitter, each control signal being transmitted at a different frequency corresponding to the at least one radio-control transmitter from which the control signal was transmitted, each control signal having a frequency which corresponds to an instructive value of radius of curvature to be generally followed by at least a subset of said, drones and which increases and decreases with said instructed value of radius of curvature;receiving each control signal with said receiver in respective of said drones;detecting at respective of said drones instructive values of radius of curvature corresponding to the different apparent frequencies of the control signals;weighting at each of said drones the instructive values of radius of curvature and forming a weighted instruction value of radius of curvature; andactuating a rudder unit in respective of said drones so as to guide respective of said drones along respective paths corresponding to said weighted instruction value of radius of curvature that was formed in each of said drones in said weighting step.
