Possible EW site?

Project Ibex was launched in around 1974, with Iran and the USA as equal partners, however, Iran paid almost the entire cost of the project, some $500 million, to the main US contractor - Rockwell Inc. Project Ibex was a joint CIA+NSA / Iran enterprise for building and operating a series of observation and listening posts along the Soviet border and at other locations around Iran. There were five ground stations; three jointly run by the IIAF/USAF crews and two operated by the CIA or, more likely, the NSA. The CIA-crewed stations were established at Bushehr (Tracksman 1) and at Kapkan (Tracksman 2). The most distinct functions of these five intelligence-gathering stations were: to monitor the radio and telemetry traffic of the Soviet armed forces in southern USSR, especially to find evidence of heightened military activity; to monitor Soviet missile testing; and to receive high resolution photographs from the orbiting spy satellites. http://www.spyflight.co.uk/darkgene.htm The earliest, and still common, means of direction finding is to use directional antennas as goniometers, so that a line can be drawn from the receiver through the position of the signal of interest. Locating the transmitter's position is usually part of SIGINT. Triangulation and more sophisticated radio location techniques, such as time of arrival methods, require multiple receiving points at different locations. These receivers send location-relevant information to a central point, or perhaps to a distributed system in which all participate, such that the information can be correlated and a location computed. http://en.wikipedia.org/wiki/Signals_intelligence
