1. A method of measuring residue ejected from an agricultural machine as the agricultural machine harvests a field, the method comprising:
transmitting an electromagnetic pulse toward a volume generally rearward of the agricultural machine;
measuring a reflection of the electromagnetic pulse;
determining velocities of masses represented in the measured reflection;
based at least partially on the determined velocities of the masses represented in the measured reflection, distinguishing reflections from ground from reflections from residue ejected from the agricultural machine;
calculating a property of the residue ejected from the agricultural machine based on the measured reflections from the residue;
calculating a location at which the residue is expected to land in the field; and
generating a residue map correlating an amount of residue with locations in the field.
