VTOL/Helicopter approach and landing guidance sensors for Navy ship applications

摘要

Approach and landing guidance sensors essential to recover V/STOL aircraft and helicopter on ships are described. Alternative techniques which feature different operating frequencies from microwave to optical-infrared, different geometric techniques of position fixing by range and angle measurements from a single point or points on a short baseline available at the landing platform typically forty feet wide are included. Other factors discussed include ceiling/visibility requirements, in-close accuracy, safety and pilot acceptance, and compatibility with air traffic control and landing systems.
