Abstract
The Doppler frequency shift of coherent light reflected from moving objects is used to obtain resolution much greater than the classical limit for imaging systems. The Doppler information is processed by using the temporal and spatial filtering properties of modulated reference wave holograms formed with a reference wave having a range of frequencies across it matching the Doppler frequencies received from the moving object.
