AN/APQ-72
AN/APQ-72 is an X-Band tracking radar used in the McDonnell Douglas F-4B Phantom.
The parabolic reflector had a diameter of 32 inches (81 cm). A target tracking was performed with the conical scan. The complete cutler feed of the antenna rotated and was eccentrically mounted by a few millimeters. The antenna can scan a sector of 120 degrees and its elevation angle can be adjusted to a maximum deviation of ± 60 degrees from course. The target illumination radar AN/APA-128 for guiding AIM-7 Sparrow missiles was integrated into the system. The dipoles visible in the picture belong to the AN/APX-76 IFF-interrogator. This was retrofitted during the Vietnam War as an upgrade.
