METHOD FOR DETERMINING COORDINATES OF RADIO EMISSION SOURCE Russian patent published in 2018 - IPC G01S5/04 

FIELD: radio engineering, communication.

SUBSTANCE: invention can be used for high-precision determination of the coordinates of radio emission sources (RES) with the aid of aircrafts, emitting continuous or quasicontinuous signals. The method of determination of the RES coordinates is RES signal receiving on three aircrafts, their relaying to the central point of processing and computing RES coordinates using radial velocity differentials, while additionally Doppler frequency shifts are there as a maximizing argument of amplitude spectrum of the product of a signal from one repeater by a signal from another repeater, subjected to complex pairing and shift for a time delay, which is defined as a maximizing argument of the function module of the mutual correlation of converted signals, obtained by multiplying the original signals by the same signals, subjected to complex pairing and temporary shift by the interval T, exceeding the value, which is inversely proportional to twice the spectrum bandwidth.

EFFECT: reduced hardware costs when implementing a method based on the products of functional electronics, and when implementing a method, based on digital signal processing hardware, improving the response time by reducing the amount of arithmetic operations.
