RANGING METHOD AND DEVICE TO DETERMINE COORDINATES OF RADIATION SOURCE Russian patent published in 2014 - IPC G01S5/00 

FIELD: measurement equipment.

SUBSTANCE: invention relates to the field of determination of location of radiation sources. The specified result is achieved by the fact that at least in three mutually distanced points of reception, levels of a radio signal are measured from the source of radiation with available energy characteristics, which characterise the value of signal attenuation in the distribution channel, then, by the value of this attenuation, the distance is calculated from the object of radiation to each of the receiving stations, and using the coordinate information on location of the receiving stations, they calculate coordinates of the object of radiation. The device to determine Cartesian coordinates of the source of radiation includes at each point of reception: a non-directed antenna sensor of a half-wave vibrator; a radio receiver with an analog-digital converter at the outlet; metres of energy or amplitude of the received signal; a calculator of the distance from the source of radiation and one that combines data at receiving stations, a calculator of coordinates of the source of radiation. Coordinates of the radiation source are calculated according to formulas given in the text of invention description.

EFFECT: detection of coordinates of location of a source of radiation of available intensity in passive mode under conditions of no mutual time synchronisation of receiving stations.
