As development proceeded, the restric-tions imposed on the antenna structure as well as the aircraft wing designresulted in the linear array scanner being housed in an appropriate separateair foil and attached to the aircraft fuselage (Fig. 62). The above study resulted in the development of the AN/APQ-7 radarequipment, operating at the X-band of frequencies. This equipmentprovided facilities for radar navigation and bombing.

The AN/APQ-7 antenna consisted of an array of 250 dipole structuresspaced at | wavelength intervals and energized by means of coupling probesextending into a variable width waveguide. The vertical pattern wasarranged to exhibit a modified esc distribution by means of accuratelyshaped flaps attached to the assembly. Written by L. W. Morrison. * A large part of the antenna development was carried out at the M. I. T. RadiationLaboratory. 316 BELL SYSTEM TECHNICAL JOURNAL.
