Eliminating boresight error of an aerial due to refraction through an associated radome

摘要

The boresight error and boresight error rates in an aerial system shrouded by a radome is eliminated by measuring and storing errors of refraction induced by the radome during a test phase and subsequently making use of the stored values representing the errors in conjunction with actual values of the aerial position to determine the true direction of a target from an apparent direction as seen by the aerial.
