The concept of a backscattering coefficient of a layer of isotropic scatterers averaged over a frequency band determined by the spectral characteristics of the transmitted signal and of the receiving equipment is introduced. The coefficient is evaluated for special cases of signal and receiver spectral shapes; numerical results of practical utility are included. The analysis neglects interaction effects among the scatterers and time variations of the medium.
