System and method for locating a target using a transceiver array

A method for locating and/or tracking at least one target with a network of transmitter/receivers, called sensors, of which at least part have a known geographic location, each comprising data processing means implementing at least one algorithm for locating and/or tracking target(s), means for transmitting/receiving a signal that decreases with distance and communication means, the network of sensors covering at least one geographic area, called the region, the method comprises, for each instant (t), an iteration of the following steps:

• selection of a sensor, called the leader, for each target, using at least one leader selection algorithm, for the implementation of the subsequent steps,
• exchange of data, called similarity data, between the leader sensor and at least part of the sensors in the network, these data being representative of power measurements of the signal between the sensors and the target and between the sensors themselves,
• determination of a probability distribution of the position of the target in the region by the leader sensor, using at least one probabilistic matrix regression algorithm, determining, on the basis of the similarity data, a probability distribution of the scalar products between the positions of the sensors and the positions of the target, for estimating said probability distribution of the position of the target.
