A two-day Radio Frequency Interference Seminar,
sponsored by the IRE Professional Group on Radio Interference
and the Air Research and Development Command of USAF, was held
in New York on June 15 and 16. This seminar was attended by a
total of 250 radio interference engineers, together with representatives
of Rome Air Development Center, Wright-Patterson Air Force Base,
Bureau of Aeronautics, U.S. Navy, U.S. Army, Air Research and
Development Command of the U.S. Air Force, and the Federal Communications
Commission.
The first day was an unclassified session held at the Park Sheraton
Hotel. The seminar chairman, Mr. S. J. Burruano, of the Filtron
Company, arranged for a most informative program which included
a morning session of interference predictions.
The afternoon session, with Mr. E.W. Chapin of the Federal Communications
Commission as moderator, had a national panel of interference
measurement experts on the stage. The interference measurement
forum started off with a brief talk by several of the panel members
who provided information on the latest interference measurement
techniques. The seminar was then opened to the floor for questions
from the assembly. Members of the panel were R. J. Farber of Hazeltine
Research Corp., A. L. Albin of Filtron Company, L. B. Wilson of
Sperry Gyroscope Company, R. B. Schulz of Armour Research Foundation,
A. T. Parker of Stoddart Aircraft Radio Company, M. T. Harges
of Empire Devices Products Corp., A. H. Sonnenschein of Polarad
Electronics Corp., C.S. Vasaka of U. S. Naval Air Development
Center, and S. Skolnik of Wright Patterson Air Force Base.
The classified session of this seminar, held on June 16 at the
Main Auditorium of the Albert Einstein College of Medicine and
sponsored by the Air Research and Development Command of the U.S.
Air Force, was the first classified seminar ever held on the subject
of radio interference.
Mr. Leonard Milton, Executive Vice President of the Filtron Company
and Vice Chairman of the Professional Group on Radio Frequency
Interference, introduced the keynote speaker, Colonel C. H. Lewis,
Director of Electronics, Headquarters, ARDC, Washington , D. C.
Colonel Lewis, in a brilliant address on the subject of radio
interference, brought out many of the problems of the Air Force
due to radio interference and stressed the recommendation that
radio interference be considered in the initial stages of design
of all new weapon system programs. He also stressed the requirement
that throughout the entire program, continued top level radio
interference efforts be continued so as to provide a weapon system
that can operate without malfunction in the electronic environment
for which it was designed. He also stressed the fact that the
electromagnetic spectrum is a natural resource and must be conserved
and utilized carefully, because this natural resource has its
physical limitations. Once we use it up or contaminate it with
interference signals of all kinds, then it has limited usefulness.
A paper entitled “Electromagnetic Interference Analysis and
Control for Compatible Military Operation” was presented
by Mr. Joseph Berliner of the Rome Air Development Center. Mr.
A. L. Albin and Mr. Murray Gunar of the Filtron Company presented
a paper entitled “Interference Analysis in the Ballistic
Missile Early Warning System.” Many new techniques and devices
were shown on the screen and described in this paper which indicated
that the state-of–the–art has been advanced.
A most comprehensive paper was presented by Mr. Leonard Milton,
Executive Vice President of the Filtron Company, entitled “Methods
of Signal Density Measurements.” This paper, which was illustrated
by over 50 colored photographs, described an electromagnetic radiation
analysis that was taken of Thule Air Force Base and the Arctic
vicinity by the Filtron Company last summer. Described were the
methods of measurement. Shown were the radio interference vans,
fully equipped for automatic measuring, and the data obtained
and the calculations and analysis were presented.
Mr. E. R. Radford of the General Electric Company, Syracuse, presented
an outstanding paper on “RF Power Density Evaluation and
Measurements of AN/FPS-7 Radar System.” Mr. Radford’s
paper was supplemented by over 40 photographs of the system. He
described the methods, instrumentation, and results of the measurement
program, together with an evaluation and analysis of the data.
Other outstanding papers were presented by Mr. W. B. Floyd and
Mr. A. L. Fullerton, Jr., of Melpar, entitled “Interference
Prediction Utilizing a Digital Computer” and Dr. H. A. Meyers
of the Rand Corporation who spoke on “Effects of Dense Radar
Distributions in Receivers.”
This classified symposium was attended by interference engineers
and experts throughout the country, and was acknowledged by military
interference experts as the most informative and technically up-to-date
of all the interference symposia held so far. EMC
