In addition to being used to calibrate signal strengths and polarizations the dihedral reflector can be used to check the location accuracy of points in a radar image. A trihedral reflector is more commonly used for strength and location measurements but a dihedral can produce specific polarization responses that are not possible with a trihedral. 3, record 1, English, - dihedral%20reflector

Le réflecteur dièdre est utilisé pour étalonner des intensités et polarisations du signal mais peut aussi être utilisé pour vérifier les précisions d'emplacement de points d'une image radar. On utilise plus couramment un réflecteur trièdre pour mesurer l'intensité et l'emplacement mais un dièdre peut produire des réponses de polarisation particulières qu'on ne saurait obtenir d'un trièdre. 3, record 1, French, - r%C3%A9flecteur%20di%C3%A8dre
