Bearing Readout Techniques for Goniometric Direction Finders
Abstract
A bearing readout system reflecting earlier developments at the Naval Research Laboratory has been installed for use in connection with the wide-aperture direction finder developed by the Laboratory. An 1800-tooth tone wheel is mounted on the goniometer shaft and pulses derived from its signal are fed to a counter which contains the instantaneous azimuth to the nearest 0.1 degree. This azimuth data is sent to a number of remote units, each of which contains an analog-digital converter for presetting an azimuth. At the moment of equality of the preset and instantaneous azimuth, a pulse is generated to form an electronic alidade. Bearing readout is achieved by reading the preset azimuth on a digital printer. Continuous visual digital display of the preset azimuth is also available.
