AN/APQ-180

The AN/APQ-180 is an all-weather, multi-mode radar which was developed by Raytheon from the APG-70 for the AC-130U Specter gunship aircraft. This X-band pulse-doppler radar is designed for both air-air and air-ground missions; they are able to look up at high-flying targets and down at low-flying targets without being confused by ground clutter. The APQ-180 radar has fixed target track, ground moving target indication and track, projectile impact point position, beacon track, and a weather mode. The AN/APQ-180 system uses a modified gimbaling scheme for the planar array, and an upgraded analog signal processor unit, and incorporates several enhanced (and new) air-to-ground modes.
