| 1. A method of measuring the speed of air in a zone of the atmosphere by the Doppler effect using a radar, the method comprising
the steps of:
transmitting bursts of three pulses at different rates F1, F2, F3;
determining respective speeds V1, V2, V3 of the air from the pulses received in return from the pulses in each burst; and
calculating the speed V of the air from the speeds V1, V2, V3 determined for the returned pulses received for each burst.
