METHOD FOR DETERMINING RADIO-FREQUENCY EMISSION SOURCE COORDINATES Russian patent published in 2007 - IPC G01S5/02 

FIELD: radio engineering.

SUBSTANCE: method involves receiving radio emission sources signals in given frequency bandwidth ΔF by means of measuring instrument moving in space, measuring primary coordinate information parameters of the detected signals with secondary parameters being simultaneously measured and stored like measuring instrument position coordinates, repeatedly measuring a set of primary and secondary parameters when the measuring instrument is moving along free trajectory. Signal level is used as the primary coordinate information parameter. The signal levels are measured at N points, (N≥4), when the measuring instrument moves. N-1 signal level ratios are calculated in turn. The calculated values are used for building N-1 circular lines defining location and radio emission sources coordinates are determined as points of intersection of N-1 circular location lines. Increase in accuracy in determining coordinates of radio emission sources is achieved due to C² _N circular lines of position being used, where C² _N is the number of all various combinations of N things 2 at a time, (N≥4).

EFFECT: enhanced effectiveness in determining radio radiation source coordinates with single moving measurement instrument; simplified radio control means configuration.
