Continuous-wave CO2 laser radars have generally been considered for the task of detecting moving targets (MTI).1 After acquiring a target the object could then be imaged by a pulsed-ranging laser radar. However, it is also possible to image the target in Doppler space with a cw laser. A high-resolution velocity image contains a great deal of information useful for target classification. The advantage over conventional imaging systems is the ability to reject stationary background clutter.
