ABSTRACT:
A system comprised of a one or more rapidly flashing thermal image beacons, a plurality of sensors, a control subsystem, input means, and a power source. Each beacon being comprised of a precision machined and polished parabolic or elliptical mirror. A resistive heating element is nominally positioned at the mirror focal point. The heating element is mounted on a carriage which can be moved backwards and forwards by a microprocessor-controlled mechanism. The resulting oscillatory action creates a rapidly changing coded flashing thermal image.
