ELECTRONIC OBSERVERS FOR RADIO DIRECTION FINDING,
Abstract
Automated bearing readout methods are investigated for the Wullenweber wide-aperture radio direction finder, with particular attention to the effects of amplitude modulation on bearing readout. An examination of a generalized RDF system is given to show the potential effects of the various components on bearing readout accuracy, and the state of the art in RDF systems and readout methods is reviewed. T The system to be used for this study, the Wullenweber wide aperture set, is described in detail, noting the pertinent characteristics for this study. Some statistical characteristics involved in readout problems are discussed and the three basic requirements for the application of Wiener's work in time series are noted, along with the nature of the output ensemble from the DF receiver. Tchebysheff's inequality is applied to the prediction of sample size requirements, and some sampling rate considerations are noted in the light of the predicted sample sizes.
