Raytheon Broadens Application Of Rotman Lens Technology
Goleta, Calif.—Raytheon’s Electromagnetic Systems Div. here is developing two key aspects of electronic warfare—listening for enemy signals and active jamming of those signals. Much of the division’s current product line and future plans exploit the Rotman lens, a type of antenna array that can simultaneously monitor and find the direction to a number of signals, or simultaneously jam on several bearings (AW&ST Apr. 14, 1986, p. 95). However, Raytheon ESD also is looking at other technologies appropriate for its future systems, such as interferometer antennas to improve direction-finding resolution.
