Abstract : A system for detecting the movement of a remote object comprising transmitting means for illuminating said remote object with a signal of wave energy, receiving means for recovering an echo reflected by said object, signal display means responsive to said echo to provide a separate visual display of each cycle of said reflected echo, and frequency comparing means responsive to a difference in frequency between the wave energy of said received echo and the wave energy of said transmitted signal to vary the orientation of said visual indication from a reference orientation, whereby a variation in said orientation will provide an instantaneous indication of a doppler effect on said transmitted wave energy.
