Hi Wayne
I dont know what frequency your working on there, but smoke probably has some effect of diffraction and scattering due to the differing densities of the smoke compared to normal troposphere, becoming greater as the frequency increases, to a point where it would almost completely be scattered or reflected at microwave frequencies.
BoM rain radars can plot smoke on the rain radar screen when its severe enough and thus must be a reflection of the signal back to the receiver.
