A METHOD FOR ELECTRONICALLY BEAM FORMING ACOUSTICAL SIGNALS AND ACOUSTICAL SENSOR APPARATUS |
摘要 |
A predetermined characteristic of amplification in dependency of the directi on (.theta.) firm which acoustical signals are received at two spaced-apart acoustical/electrical transducers (1, 2) is formed in that repetitively a mutual delay signal (A10) is determined from the output signals of the transducers and according to the ion delay at the transducers, one (S1) of the output signals is filted thereby the filtering transfer characteristic is controlled in dependency of the mutual delay signal (A12). The output signal of the filtering (14) is exploited as electrical reception signal (S r).
