摘要： Method of measuring the velocity of an aircraft at a given instant, by laser Doppler anemometry, by performing the steps of acquiring a backscattered signal on at least three oriented line-of-sight axes, and calculating the spectrum of the backscattered signal on each of the line-of-sight axes. Further, acquiring an additional backscattered signal on at least one additional line-of-sight axis (X4) not coincident with one of the three first line-of-sight axes (X1, X2, X3), and calculating the spectrum of the backscattered signal on the additional line-of-sight axis (X4). Several candidate velocity vectors ({right arrow over (V)}c) and of the projections of the candidate vectors on at least one line-of-sight axis (X1, X2, X3, X4) are calculated. The consistency of the candidate vectors ({right arrow over (V)}c) is calculated as a function of their projections and as a function of each spectrum of the corresponding backscattered signal on the respective calculation axis (X1, X2, X3, X4). The measured velocity vector ({right arrow over (V)}c) is chosen from among the candidate velocity vectors ({right arrow over (V)}c).

摘要： The invention relates to an optical measurement device intended for determining a relative velocity vector {right arrow over (v)} of a carrier, such as an aircraft, with respect to a reference medium MILREF. The device includes an optical signal system EMIREC, delivering an optical signal Sinc that follows a direction called the line of sight LDV and is concentrated in a focusing zone ZOF, and means for displacing the focusing zone ZOF in the reference medium MILREF. According to the invention, the means for displacing the focusing zone ZOF act on the orientation of the line of sight LDV, subjecting it to a known movement, with a nonzero speed, a processing unit UTR determines the vector {right arrow over (v)} in at least one “search” phase based on an identification with an expected waveform of the variation in frequency of an electrical signal as a function of the orientation of the line of sight LDV in order to determine an approximate value of {right arrow over (v)}, followed by a “tracking” phase based on an iterative validation of values of {right arrow over (v)} close to the approximate value of {right arrow over (v)}.
