About the Association of Old Crows


small crowThe Association of Old Crows (AOC) is the world's premier organization of professionals engaged in the sciences of Information/Electronic Warfare. Its international membership includes scientists, engineers, managers, operators, educators and military personnel from industry, the military services and the defense departments of several nations. Both corporate and individual memberships are available.

The AOC was organized in 1964 to provide a forum for the exchange of information on the technical and operational aspects of Electronic Warfare. It has since grown to over 75 chapters with more than 17,000 members in the United States and foreign countries. The Association of Old Crows works for the advancement of the state-of-the-art and the knowledge of electronic defense subjects with the full cooperation of the United States Department of Defense and defense organizations of Allied nations by conducting technical symposia and other educational programs.

The AOC has been in the forefront of information warfare from both operational and technical perspectives long before information warfare became a buzzword of the 1990s. By definition Information Warfare encompasses all the facets of Electronic Warfare and adds some ''orphans'' to the mix. Most of these ''orphans'' are a result of the improvements in microtechnology. All of them employ ''electronics,'' whether it is radar imagery, infra-red or electro-optical countermeasures, or computers and communications.

Origin of Name

The name ''Old Crows'' emerged from the first large scale use of EW during World War II. The radio receivers and transmitters used to monitor enemy transmissions and to jam enemy radio and radar frequencies were assigned the codename ''Raven.'' Operators who manned the equipment for those missions were known as ''Raven Operators.'' Common jargon later changed the name ''Raven'' to ''Crow.'' The term ''Raven'' is still used today in the U.S. Air Force to describe the activities performed by intercept operators. Additionally, the Air Force's EF-111 countermeasures and jamming aircraft, used extensively in the Gulf War, proudly carries the name ''Raven.'' The Association, like the Raven operators, adopted the crow with the electronic foot as its logo, and the crow is registered with the U.S. Patent Office as the official logo of the Association.

Journal of Electronic Defense

The Association's professional journal, the Journal of Electronic Defense, is the leading authoritative magazine in its field. Provided to each member monthly, it is an interesting and educational source of information on all aspects of IW/EW, C2W and related subjects. In addition, it is used by the Association to communicate with AOC members about Association activities.

For those interested, there is an Electronic Warfare Tutor.

This area of the site provides a tutorial which is intended to provide fundamental definitions and descriptions of the various principles of radar systems with emphasis on target acquisition and tracking plus weapon guidance systems.

A proper understanding of these principles is necessary in order to derive an appreciation for the operational use of Defensive Electronic Countermeasures (DECM) and digital Threat Warning Systems (TWS).

The tutorial concludes with a brief section on the generic system concept of digital Radar Warning Receiver Systems (RWR) with reference to certain specific systems on which more information can be provided in an advanced course on Passive EW.


Old Crows Is Just Our Name . . . 
Information Warfare Is Our Game!

With over 13,000 members internationally, the Association of Old Crows is an organization for individuals who have common interests in Electronic Warfare (EW), Electromagnetic Spectrum Management Operations, Cyber Electromagnetic Activities (CEMA), Information Operations (IO), and other information related capabilities. The Association of Old Crows provides a means of connecting members and organizations nationally and internationally across government, defense, industry, and academia to promote the exchange of ideas and information, and provides a platform to recognize advances and contributions in these fields.
