Abstract :
The Joint STARS radar antenna is a 24-ft-wide by 2-ft-high planar X-band slotted array scanned electronically via ferrite phase shifters to +or-60 degrees in azimuth and scanned mechanically to +or-100 degrees in elevation. It is mounted inside a radome underneath the fuselage of an E-8A aircraft, and operates in both a mapping and a three-port interferometer azimuth target tracking mode. The antenna´s five unique features are a collinear slotted array aperture, a switchable dual-mode aperture, multifunction electronic phasing, automated phase alignment, and triple temperature compensation.<>
