Environmental Interference Study Aboard a Naval Vessel

A study of nonlinear environmental sources of interference was conducted under controlled conditions aboard the aircraft carrier, the USS "Bunker Hill". Nonlinear sources were located, tested to determine their interference-contributions to nearby receiving antennas and then removed. Recommendations based on this work were incorporated by the Navy as structural modifications for existing ships and changes in new ship design. Conclusive evidence was obtained that a ship can be "cleaned-up" by locating and removing environmental nonlinearities.
