Abstract: An updating control system for two channel direction finders which includes dual loop antennas and a sense antenna; and circuits for setting the direction finder to a ''''Frequency'''' condition during which the direction finder may be tuned to a new frequency and to a ''''Bearing'''' condition in which bearings corresponding to the new frequency are taken. Individual amplifying means are provided to connect each of the two loop antennas to a plate pair of a cathode ray tube. Circuits are also shown for updating (adjusting) the phase and gain of the two signals, and for interconnecting the inputs of the two amplifiers during the updating process and for instrumenting correction of quadrantal errors.

Abstract: An updating (calibration) system for two channel direction finders comprising two loop antennas and a reference (sense) antenna. Individual receivers connect each of the two loop antennas to bearing measuring means and means are included for updating the gain and phase of the two receivers to equality. Apparatus is also included for interconnecting the input of the two receivers during the updating mode of operation to facilitate calibration (equalization) of the channels. A common signal source which is either the reference (sense) antenna or the one of the two loops having the greatest signal at the time, is applied to both signals through artificial antenna devices which are actually equalizers for calibration purposes.
