Abstract : A digital simulation of the University of Illinois Wullenweber radio direction finding system has previously been reported. This study reports the first large scale use that has been made of the digital model. It also reports certain improvements that have been made in the model that were necessitated by certain systematic errors which developed under special conditions in the original model. The experiment that has been simulated is the construction of 50 such systems, each of which has its 120 cables drawn from a population normally distributed about some mean value. The standard deviation of this distribution is variable. The effects on the system performance of these distributions are determined under varying conditions of signal frequency and elevation angle of arrival. (Author)
