Abstract :
A modified Doppler technique is discussed, whereby a moving object is simultaneously illuminated by two intersecting laser beams which are coherent with one another. By comparing the different Doppler-shifted signals scattered, refracted, or diffracted from two overlapping light beams at the object, the velocity of high-speed missiles has been measured with good accuracy.
