Radio transmission method and adapted radio transmitter

A method for generating a radio signal in a radio emitter, wherein said method comprises steps of generating, with a programmable frequency modulation generation integrated circuit, a radio carrier signal having a main frequency f and an offset frequency f+Δf and a step of providing phase modulation of said radio carrier signal by the successive generation and transmission of said main frequency f and said offset frequency f+Δf, the offset frequency having a frequency difference suitable for simulating a given phase shift of the main frequency at the end of a given time T;

• and wherein the modulation is a binary phase modulation, the given time T being the time needed to obtain a phase shift of π that can be detected by a receiver receiving the signal, said method comprising further at least one step of generating a signal with the base frequency f, at least on step of generating a signal having the offset frequency f+Δf, at least one step of transmitting the signal with the offset frequency for the time needed for a phase shift of π after transmission of the signal with the base frequency f and at least one step of return to the signal with the base frequency f when the phase shift of π is obtained.
