Abstract The scatter spectrum of radio waves by a dusty plasma has been studed with the dynamic factor which was derived from the kinetic theory. It is found that for the case of cooled electrons kλ_D<<1 (λ_D is the Debye length, and k=|k|=|k_s-k₀|, k₀ and k_s is the incident and scatter wave vector, respectivly) the dusty paticles play an important role in the scattering due to its huge charge number. There is a characteristic spiky fine structure in the scatter spectrum, which is of the dust-acoustic wave frequency shift.

Key words： Dusty plasma Dynamic factor Incoherent scatter Scatter spectrum
