Abstract

A method of guidance by radio focusing includes a “visitor” entity heading towards a radio source of number k=1 (or k=klast) by observing intensity of the radio source of number k=1 (or k=klast) as measured by an “Evisitor” communicating device carried by the visitor, until the visitor reaches the source of number k=1 (or k=klast). The visitor heads in succession for k=1, 2, . . . , klast-1 (or in reverse) from a radio source of number k towards a radio source of number (k+1) (or (k−1)) by observing intensity of the source (k+1) (or (k−1)), until the visitor reaches the source (k+1) (or (k−1)). Each radio source is a virtual radio source as produced by a respective signal k or by superposing a plurality of respective signals k. Each signal is transmitted by a respective communicating device ER.
