Background. The passive method of direction finding does not allow measuring the range to a radio emission source (RES) using the classical single-position method. One of the ways to solve this problem is to use multi-position direction finding stations. However, at the same time, difficulties arise in determining the coordinates of the RES, due to the following features of the method: direction finding stations are located on aircraft (AC), and RES – on the earth's surface; on board the aircraft it is possible to place only linear antenna arrays, which make it possible to determine by the phase method the bearing of the RES in only one (horizontal) plane. The difference in the heights of the location of the object and the RES leads to errors direction finding measurements, which reduces the accuracy of determining the coordinates of the RES. With the practical use of this method and the construction of equipment, these features must be met. For this, it is necessary to introduce algorithms for correction, compensation, and maneuver to reduce the influence of the angle of sight of the RES on the accuracy of direction finding. The purpose of this work is to reduce the errors in determining the direction finding and coordinates of the RES.
