ABSTRACT:
An improved omnidirectional radar retroreflector and marine personal locator incorporating same. One embodiment of the radar retroreflector includes first and second collapsible radar reflective disc portions biased in a substantially perpendicular open position with a plurality of radar reflecting web sections extending substantially perpendicularly therebetween creating eight sets of three mutually-perpendicular radar reflective surfaces forming an omnidirectional radar retroreflector. In a collapsed position, the first and second disc portions bend around a common axis of intersection in a non-destructive manner folding the web sections. A second embodiment of the radar retroreflector consists of a balloon having, when inflated, two intersecting disc-shaped portions oriented substantially perpendicularly and a plurality of radar reflecting web sections extending substantially perpendicularly therebetween creating eight sets of three mutually-perpendicular radar reflective surfaces and forming an omnidirectional radar retroreflector. A marine personal locator, prior to activation, restrains the radar retroreflector in a collapsed position. The radar retroreflector opens upon activation and is suspended on a tether by a balloon. The marine personal locator can also include a light source and a radio transmitter. Prior to activation of the marine personal locator, all components can be contained within a housing.
