Acoustic measurements
The context is acoustic measurements using passive sonobuoys. In a list under the heading "Types of measurement", we have "Mesures d'interférences (fond, surface), avec taux gramme de préférence". Rategram???

Typo seems likely...
In the context of acoustic measurements, I would say that there is a high probability that 'gramme' is indeed a typo for 'gamme', which would make a LOT more sense.
As FrenTur has said, it seems to be talking about something to do with passband; I would take 'taux gamme de préférence' to be something like 'capture bandwidth' or even 'level within passband'
These are only vague suggestions, David, as I can't quite get my head round the snippit of context; maybe your wider text will make things a little clearer, at least in terms of how the term is being used here.
If you have more context that could help, I might possibly be able to come up with something more intelligent.

Thanks, David, for that additional context; makes a bit more sense now, though I\'m afraid I don\'t have the specialist knowledge to be able to give you a definitive answer.
I agree entirely with you about mistrusting Eurodicautom --- it\'s come up with som real howlers in certain areas where my specialist knowledge meant I was sure of my ground!
I still have some doubts about the word \'gramme\' --- why would they use this to refer to a \'lofargram\' [clearly the English word for it...] --- don\'t you think they would either translate it into a French equivalent, or call it simply \'gram\'?
All I can say is that in all kinds of signal measurement apps. (be it sonar, radio, audio, etc.) passband / capture band / bandwidth are important factors in interpreting the measurements and dealing with the uncertainty in them. \'Gamme\' is a word logically enough often associated with a \'frequency range\', so does have some possible connection here.
I think you might be right about the \'de préférence\', but frankly I still can\'t make a lot of sense out of it.
I\'ll put my thinking cap on and get back to you if I come up with anything useful (I do have some friends who work in sonar)

Interesting, David! I don\'t think I\'d ever have guessed THAT in a month of Sundays! \'direct/reflected ratio\' -- indeed

Eurodicautom gives "capture rate" for "taux de préférence"

Discussion
As far as the "bands" are concerned, you're right of course. The kit comes with high-pass, low-pass and band reject filters.
Anyway I've asked the agency to contact the client to see if there is a typo or not (although the client is not the author).
As far as "gramme" / "gamme" is concerned, the text talks a lot about "lofargrams" hence my reluctance to see "gramme" as a typo.
In my case, the entire document is a specification for equipment used to analyse signals from sonobuoys as part of an anti-submarine system. The queried term occurs in an Appendix entitled "Liste des mesures acoustiques � mettre en oeuvre", in a section entitled "Mesures effectu�es � partir de bou�es passives".

Les mesures acoustiques sont toujours r�f�renc�es par rapport � une bou�e. Elles doivent permettre d'extraire les �l�ments caract�ristiques d'un contact. Ce sont essentiellement des mesures de :
Fr�quence
Niveau (dB/μPa)
Azimut
Retard
Vitesse
Distance (Nautique)
Temps
A toutes ces mesures sont associ�es des incertitudes provenant � la fois des bou�es et du syst�me de traitement.
1.1 Types de mesures
Mesures d'interf�rences (fond, surface), avec taux gramme de pr�f�rence
Mesures DIFAR
Mesures Doppler CPA
Mesures de localisation (LCD/HYFIX) et LESP D/S
Ces mesures sont effectu�es par l'op�rateur � partir des images de traitement acoustique des bou�es passives d�sign�es. Les fonctions de traitement de bou�es passives mises en �uvre sont indiqu�es ci-dessous, associ�es au nombre maximal de bou�es � traiter (simultan�ment), dans la version de base.
