AbstractA lidar-based air defense system for providing a single unified system that may detect, track and even destroy airborne objects, even objects designed to move relatively undetected through conventional radar systems. The lidar-based air defense system includes a support, and a plurality of laser transmitters mounted on the support in sets of different angles. Each of the laser transmitters are adapted to transmit a coherent beam of light along an axis, with the plurality of laser transmitters being oriented such that the axes of the beams of light emitted from the laser transmitters radiate outwardly from the support to generate a grid of laser beams in the atmosphere. The system also includes a plurality of laser receivers and a processor for processing information from the laser transmitters and laser receivers.
