The high fineness ratio required by modern boresight radomes has reduced present day radome design to an art rather than a science. The radome designer must have at his disposal some means of rapidly collecting boresight shift data, which he can employ to improve or control a given radome design. This paper describes an automatic boresight measuring system, consisting of a radome mounting fixture, a radar tracking antenna and a null seeking mechanism, which can be employed to provide such data. The automatic boresight measuring equipment is able to automatically collect and record boresight data, cross talk data, and the vector sum of these two as a function of the angle of look. The accuracy of these measurements is better than 0.25 mils. This particular set of automatic boresight measuring equipment can also be employed as a radiation pattern measuring device.
