<p>Systems and methods for providing passive bird-strike avoidance. A passive L-band receiver system (20) is located on an aircraft (18). The system includes a processor (30) and an antenna (34) having an array of four or more elements. The antenna configured to receive L-band signals. The processor receives the L-band signals from the antenna, determines if the received L-band signals indicate a target, determines distance, direction of travel and speed of any determined targets, determines if the target is a flock of birds based on the determined speed and determines if a hazard condition exists based on the distance, direction and speed.</p> |
