CoherentSource models an optically rough reflector illuminated by a uniform intensity plane wave with zero tilt. The reflected return is modeled using OPDs at each mesh point computed from a fixed random surface model. CoherentSource is a composite system, containing two subsystems, a UniformWave and a CoherentTarget. It has a single Light output, representing the transmitted light. See also IncoherentSource.
