DATA LINK OF LARGE AMOUNTS OF ANTENNA TRACKING RECOVERY DEVICE AND METHOD

摘要

PURPOSE: A massive data link antenna tracing recovery device and a method are provided to easily grasp the location of an airplane by using special communication devices when an aircraft is not traceable. CONSTITUTION: A ground antenna tracer traces airplanes based on signal. A first beam width antenna receives a first declining link reception signal. A second beam width antenna receives a second declining link reception signal. An aircraft control information generator generates aircraft control information. A duplexer combines uplink transmission signal and downlink reception signal.
