The inappropriateness of point scatterers for time-dependent classical wave scattering is addressed. An alternative model in terms of a lowest-order pole expansion is simple and well behaved. The propagator of a homogeneously disordered medium is calculated with the alternative method. A delayed signal or code that depends on the microscopic parameters of the scatterers is observed. These results support speculations that the code contains important information about a disordered medium that might be relevant for imaging applications.
