Abstract : The patent describes an invention for determining the direction and distance of a remotely located radio source. It is based on the principle that the distance to a station is inversely proportional to the root mean square value or peak value of the received continuous bearing signal as a function of time which has first been passed through a twenty minute averaging or smoothing window.
