Interpolation Charts for HF-F Shipboard Calibration
Abstract
An investigation has been made to determine means for providing convenient and accurately corrected Naval shipboard direction finder bearings for any frequency within the h-f direction finder band without requiring more than a limited and feasible number of specific calibrations of the equipment. Interpolation charts have been developed which simplify the plotting and application of direction finder calibration curves and furnish the desired corrected d-f bearings for the calibrated and for all other frequencies between those on which calibrations have been made. Means are discussed for choosing the optimum number and spacing of frequencies to be calibrated in terms of the probable interpolation accuracies that may be expected. A practical rapid calibration method is proposed to improve the efficiency and accuracy of making calibrations.
