Abstract :
The forward-scatter compled amplitudes of spheroidel ice and water particles are evaluated at 20 and 30 GHz by using a field a point-matching method. The crosspolarisation resulting from a group of identical equioreintated particles is then derived. It is seen that equiorientated ice particles can cause significant crosspolarisation with little attenuation, in agreement with recent measurements of crosspolarisation on satellite paths.
