Abstract :
Correlation measurements at linear polarisation in dual-channel precipitation radars are investigated. It is shown that the correlation between orthogonal linearly polarised back-scatter components provides information on precipitation particle orientation and shape. Thus, as is the case at circular polarisation, correlation measurements can be a useful concept for particle identification. Preliminary results from measurements made at 9.6 GHz are presented.
