Exact inverse-scattering equations are derived for the time-domain plasma-wave equation. Care is taken to motivate each step of the derivation by elementary physical arguments. The inverse method in this formulation is shown to depend on (1) causality, (2) the far-field properties of the Green function, and (3) the representation theorem.
