Abstract:
A method of enabling a small water craft or a person in said water craft to reduce possibility of a collision, by causing a reflection of a radar signal to enhance detection of the water craft or person in the water craft, said method comprising:a) providing a radar reflective layer in a surface area of a surface of a water craft accessory selected from a group consisting of a paddle, a life vest and a cushion said surface area having an alignment axis or an array of alignment axes perpendicular to said surface area and/or portions of said surface area;b) observing or detecting presence of a second water craft at a location where radar detection apparatus is in use or another location where radar detection apparatus is in use;c) enabling said radar detection apparatus to detect location of the water craft or person by orienting the water craft accessory so that the surface area of the surface of the water craft accessory is oriented so that the axis or array of axes of that surface area is aligned with an alignment axis from the radar detection apparatus to the water craft or person,whereby radar waves traveling from the radar detection apparatus to said surface area are reflected back to the radar detection apparatus to cause detection of the water craft or person.
