Intensité des échos
Les couleurs permettent de différencier les
intensités des échos. L’intensi d’un écho
dépend de plusieurs facteurs, notamment :
La taille de la cible (poisson, banc de pois-
sons ou autres objets).
La profondeur de la cible.
L’emplacement de la cible (c’est au centre
du cône d’ultrasons que les échos sont les
plus intenses).
La clarté de l’eau. Les particules ou l’air
présents dans l’eau réduisent l’intensité de
l’écho.
La nature et la densité de la cible ou du
fond.
Important : à grande vitesse, les coques
planantes produisent des bulles d’air et des
turbulences qui viennent bombarder la sonde.
Les interférences ultrasons qui en résultent
peuvent être captées par la sonde et couvrir
les véritables échos.
Types de fond
Les fonds meubles (vase, algues, sable)
affaiblissent et dispersent le signal ultrason et
renvoient donc des échos de faible intensité.
En revanche, les fonds durs (rochers, coraux)
réfléchissent parfaitement le signal ultrason et
retournent des échos de forte intensité. Veuillez
vous reporter à la section 5-3 “Ecran Sonar
Fond” pour plus d’informations.
