A statistical model was developed for a direction-finding site at HF 1 - 30 MHz. The model was used to analyze the effects of extended re- radiators on DF accuracy and was examined both theoretically and experimentally. An explicit expression is obtained for the probability density distribution of the electric field amplitude as a function of each of two quantities azimuthal position of the transmitter and transmitter frequency. The distribution is shown to be a one-parameter Rice distribution in each case. The parameter may be obtained by sampling over either azimuthal angle or frequency. It is suggested that this parameter be used as a single-number criterion for the evaluation of DF sites.
