This invention is an easily deployable, expendable or recoverable floating radar reflective device. The invention can be bout with sufficient reserve buoyancy to allow the fitting of a number of optional devices, such as a GPS transceiver or lighting. Thus, the device can be used for a variety of applications including: man-overboard marker, radar testing, temporarily marking submerged objects or navigation points, search and rescue, naval gunnery practice and/or weapons testing, or any other application that requires a floating reflective station. The device is constructed of aluminum, and consists of a tetrahedron shape with a floatation pod with an integrated radar reflector at each apex. Each floatation pod is fitted either with scuttling devices, to cause the device to sink if recovery is not a preferred option, or plugs if recovery is required. The use of dissimilar metal in the scuttling devices and the pins that hold the device together allows the device to rapidly corrode once it sinks, alleviating environmental concerns. The device is collapsible for ease of storage, and can be either assembled by hand, or deployed automatically, depending upon usage requirements. The tetrahedron shape allows the device to roll due to the motion of the waves or the method of deployment, and always present the same shape and reflective area as a target for radar, or as a support for optional devices mounted on the structure.
