ABSTRACT:
The invention relates to a system for measuring the velocity of a moving object with respect to the ground as projected onto an axis, using the Doppler effect. Two signals .SIGMA. + kj .DELTA. and .SIGMA. - kj .DELTA. are produced from received signals .SIGMA. and .DELTA., k being a coefficient which depends on the velocity of the moving object and on a predetermined duration T. Measuring the difference between the phase of signal .SIGMA. - kj .DELTA. and that of signal .SIGMA. + kj .DELTA. after the latter has been delayed by duration T produces a signal proportional to the velocity sought. The invention is applicable to aerial or marine navigation systems.
