A strap (10) made of a first reflecting layer (11) and a second metal layer (12), such as fabric comprising metal yarn, a metal lamina, etc. The strap (10), once coupled the two layers (11, 12) to each other, has a side showing the reflecting material (11) and the other side showing the metal layer (12). The light reflecting part (11) is carried out with a desired known reflecting flexible material, as normally used for rescue equipment for catching the eye during the night. The radar detectable part (12), even if made of metal material does not make the strap heavy to carry and to wear and, in addition to making the strap more resistant, has surprisingly the property of reflecting the electromagnetic waves in order to radar detect missing people at several miles distance. A strap portion (10) radar detectable, since it reflects electromagnetic waves coming from a radar and is light reflecting, can be arranged on rescue equipment like traditional reflecting strap portions that are not radar detectable, such as life jackets, life preservers, life rafts, etc. <IMAGE> |
