METHOD OF FINDING COORDINATES OF RADIO-FREQUENCY RADIATION SOURCE Russian patent published in 2006 - IPC G01S5/10 G01S11/00 

FIELD: radio engineering.

SUBSTANCE: method can be used for high precision measurement of coordinates of radio-frequency radiation sources which radiate continuous or quazi-continuous signals by means of flying vehicles. Method is based upon reception of signals from radio-frequency radiation sources at three flying vehicles, re-translation of signals to central processing board and calculation of coordinates of radio-frequency radiation sources from difference in radial velocities of flying vehicles. Signals being re-translated from flying vehicles are subject to additional mutual correlation processing. Difference in radial velocities is calculated on the base of measurement of compression factors determined by maximizing of mutual correlation function of signals re-translated from flying vehicles. Coordinates of radio-frequency radiation sources radiating wideband signals is provided.

EFFECT: widened functional capabilities.
