Analytical expressions are obtained for spectral energy density of an electromagnetic wave scattered backward by an axisymmetric scatterer flow. Dependence of the frequency band of a scattered signal on flow sensing angle is studied. It is assumed that wavelength is less than flow sizes, scatterers are statistically independent and distributed uniformly along flow surface. The calculation results show that the signal frequency spectrum scattered by conical flow is characterized by monotonic energy increase with increase of the Doppler frequency shift.
