Determination of the location of a ground source of radio emission using a direction finder situated on the earth's surface

Analysis of the problem of determining the geographical position of a source of radio emission with the aid of a direction finder on the earth's surface, consisting of two mutually perpendicular families of antennas. Optimal algorithms are developed for processing phasometric measurements on the basis of a criterion of maximization of a likelihood function. The algorithms permit obtaining point estimates and confidence regions for the position of the radio source in a system of coordinates related to the direction finder.
