Electronic warfare engineering

Electronic Warfare (EW) engineering is the branch of engineering concerning the use of the friendly electromagnetic spectrum to deny its effective use by an adversary.

Electronic warfare has been divided into three main divisions: electronic support, electronic attack, and electronic protection.

In military telecommunications, the term Electronic Support (ES) is the division of electronic warfare involving actions taken under direct control of an operational commander to search for, intercept, identify, and locate sources of radiated electromagnetic energy for the purpose of immediate threat recognition. Thus, Electronic Support (ES) provides a source of information required for immediate decisions involving Electronic Protection (EP), Electronic Attack (EA), avoidance, targeting, and other tactical employment of forces. Electronic Support data can be used to produce signals intelligence (SIGINT), both communications intelligence (COMINT) and electronics intelligence (ELINT).

The Association of Old Crows is a nonprofit international professional organization specializing in electronic warfare, tactical information operations, and related topics.

The name "Old Crows" emerged from the first use of electronic warfare in World War II to disrupt enemy communications and radars. Allied equipment and operators were known by the code name "Raven". In common jargon those engaged in the profession became known as "Old Crows".

The organization draws expertise and information from a pool of thousands of individuals, including technology specialists and actual military personnel. It is involved in advancing electronic warfare and information-gathering techniques, disseminating information on these topics, and supporting the education of personnel in related matter.
