ABSTRACT:
Communications link using the ionized trail of a meteor entering the atmosphere at an altitude of approximately 100 kilometers as reflectors to relay radio frequency energy beyond the horizon using a retrodirective adaptive loop. The retrodirective adaptive loop includes a plurality of conjugate antenna elements, with each conjugate antenna element having a spatial servo-loop circuit. At least two stations having antennas with conjugate elements are required for generating a retrodirective oscillating or phase locked loop.
