AN/APS-15
AN/APS-15 (alias H2X) was operating in X-Band navigation and search radar used during the end of World War Ⅱ. It was used in the B-17 “Flying Fortress” as bombing set with the nick name “Mickey”.
The antenna was a parabolic reflector fed by a Cutler feed. The reflector was modified with an additional lower lip to produce a Cosecant squared type beam in elevation. Since the radar was mounted in a small radome upside down under the fuselage of the airplane, an inverted cosecant squared pattern was created.
