Claim 3:
4. A system for monitoring an individual, the system comprising:
a first coherent laser radar section including:
a laser source that generates a first laser beam,
an interferometer that splits the first laser beam into a first target beam that is directed toward a target location on the individual and a first local oscillator beam, and that generates a first combined target beam from a first reflected portion of the first target beam returning from the target location on the individual and the first local oscillator beam;

a second coherent laser radar section including:
a laser source that generates a second laser beam,
an interferometer that splits the second laser beam into a second target beam that is directed toward the target location on the individual coincident with the first target beam and a second local oscillator beam, and that generates a second combined target beam from a second reflected portion of the second target beam returning from the target location on the individual and the second local oscillator beam;

a processor that determines a range and an instantaneous velocity for each of one or more points on the skin or the clothing of the individual over a period of time from the first combined target beam and the second combined target beam.
