Method for directional location and locating system
View Patent ↗In order to locate electromagnetic or acoustic signal sources of a sensor configuration ( 1 a through 1 c ) fitted with at least two electric outputs; where the incidence-dependent transfer functions between the acoustic signals incident on the input(s) of the sensor configuration ( 1 a through 1 c ) and the electric output signals are different, the ratio ( 7 X through 7 XX ) of the output signal is formed and the result then is correlated with the previously determined ratio function ( 11 ).
