mode de polarisation alternée

CONT: Nous élargirons cette série temporelle de mesures en incluant ENVISAT en mode de polarisation alternée.

CONT: Instead of scanning between different elevation sub-swaths, the Alternating Polarisation Mode (co-polar) scans between two polarisations, HH and VV, within a single swath (which is preselected, as for the Image Mode). In addition, there are two cross-polar modes, where the transmit pulses are all H or all V polarisation, with the receive chain operating alternatively in H and V, as in the CO-polar mode.
