1. An ultrasonic target, comprising:
a main reflector
comprising three main faces, extending from a main vertex, the main faces forming a main trirectangular trihedron by lying on orthogonal planes, and
defining a main base plane, lying facing the main vertex, and forming a base of the main trirectangular trihedron; and
at least one auxiliary reflector fastened to the main reflector, the at least one auxiliary reflector
comprising three auxiliary faces, extending from an auxiliary vertex, the auxiliary faces forming an auxiliary trirectangular trihedron, and
defining an auxiliary base plane, lying facing the auxiliary vertex, and forming a base of the auxiliary trirectangular trihedron, wherein
the auxiliary base plane or each auxiliary base plane is parallel to the main base plane,
two adjacent main faces of said main trirectangular trihedron are separated by a ridge and extending from the main vertex,
at least one auxiliary reflector is an internal auxiliary reflector,
the auxiliary vertex of the internal auxiliary reflector is located on said ridge, and
the internal auxiliary reflector is delineated by:
said adjacent main faces, forming the auxiliary faces of the internal auxiliary reflector; and
a transverse auxiliary face extending between the adjacent main faces, parallel to a main face opposite said adjacent main faces.
