AN/APQ-13

AN/APQ-13 “Mickey” is an operating in X-Band airborne bombing radar. It was used on B-29s during World War II in the Pacific theater for high altitude area bombing, search and navigation.

The antenna is a center fed feedhorn with a parabolic reflector. It forms an inverse cosecant squared pattern (because the antenna in figure 1 is installed upside down in the radome under the fuselage).

The AN/APQ-23D is identical to the AN/APQ-13 with exception of the modification kit MX-344/APQ.
