signal contrapolaire

Quotient de la puissance du signal reçu (ou émis) par une station terrienne sur une polarisation (le signal désiré), sur la puissance du signal reçu (émis) sur la même polarisation mais provenant d'un signal contrapolaire.

The ratio of the signal power received (or transmitted) by an earth station on one polarization (the desired signal) to the signal power received (transmitted) on the same polarization but originating from a cross-polar signal.

Comparison of linear and logarithmic receiver signals from polarimetric weather radar echoes and their temporal decorrelation properties...(e.g.: reflectivity, differential reflectivity, linear depolarisation ratio - for both - co-polar and cross-polar signal components) are based on the logarithmic receiver output, because of the large dynamic range provided by the logarithmic receiver....

First polarimetric gnss-r measurements from a stratospheric flight over boreal forests... For elevation angles larger than the Brewster angle, it is found that the cross-polar signal is dominant when just single reflections over the forests are evaluated, while in the case of multiple reflections the co-polar signal becomes the largest one....

Cross-polarisation discrimination-induced interference in dual-polarised high-capacity satellite communication systems... Furthermore, depolarisation-induced interference in such systems could have a performance-limiting impact if a co-channel cross-polar signal combines with system noise to drive the carrier-to-noise-plus-interference ratio (CNIR) below an acceptable threshold....
