Radar, EW & ELINT Testing:
Identifying Common Test Challenges
The roots of modern radar systems stretch back to 1940 when the U.S. Navy developed what was
then called radio detection and ranging or RADAR. Today, this technology has been adapted to
applications that range from the ubiquitous supermarket door opener, which is a simple moving-
target indicator (MTI), to highly complex shipboard phased-array fire-control radars.
In military applications, two new fields followed close on the heels of radar: electronic intelligence
(ELINT) and electronic warfare (EW). ELINT is used to extract information from enemy radar sys-
tems and provide insights into coping with potential threats attached to those radar signals: ships,
aircraft, missiles, and so on. The associated development of EW technologies provides active and
passive responses to those potential threats.
