To search for an avalanche victim wearing a radio transmitter continually transmitting at a standardized frequency, the method according to the invention comprises: a victim detection phase during which a rescue worker wearing a receiver methodically covers the zone snowed in by the avalanche during which time the receiver detects the moments when the amplitude of the signal received is greater than a lower threshold, a phase of directional search for the victim during which the rescue worker rotates with the receiver while the latter detects the moments when the amplitude of the signal received is at the maximum, and signals these moments to the rescue worker who is then pointed towards the victim, a phase during which the rescue worker advances towards the victim, during which the receiver checks that the amplitude of the signal remains at the maximum, and detects the moments when the amplitude of the signal received exceeds an upper threshold.
