Abstract

Akustik sinyallerin birbirinden bir mesafede bulunan iki akustik/elektrik transdüktörde (1,2) alindigi istikamete (0) bagli olarak önceden tespit edilmis bir amplifikasyon karakteristigi olusturulur ve burada tekrar tekrar bir müsterek gecikme sinyali (A10) transdüktörlerin çikis sinyallerinden tespit edilir ve transdüktörlerde resepsiyon gecikmesi uyarinca, çikis sinyallerinden birisi (S1) filtre edilir, ve böylece filtreleme transfer karakteristigi müsterek gecikme sinyaline (A12) bagimli bir biçimde kontrol edilir. Filtreleme isleminin (14) çikis sinyali elektrik resepsiyon sinyali (Sr) olarak kullanilir.
