METHOD OF DETECTING AND FINDING LOCATION OF RADIO-FREQUENCY RADIATION Russian patent published in 2005 - IPC

FIELD: radio engineering.

SUBSTANCE: method can be used for detection and finding of on-ground radio-frequency radiation sources. Method is based upon receiving of radio-frequency radiation in N≥3 points being distant from each other is space, transmission of data to central point, determination of R_n(x,y) distance from any point of (x,y) space to any n=1,2,...Nth point of receiving of data, measurement of efficient values f voltage of received radio signals U_n, transmission of the signals to central point where they are subject to transformation to spatial indeterminate function F(x,y). Availability of radiation and position of source are found from location and value of maximum of the function. Value and position of maximum of spatial indetermination are evaluated in neighborhood of point having coordinates to be equal to weighted average coordinates of reception points with weights being equal to measured efficient values of voltage of received radio signals raised to 4/p power. P parameter is determined while taking dependence of strength of source field into account on distance with standard value being equal to 1 or 2.

EFFECT: improved precision; increased efficiency; stabilization of false alarm level.
