Abstract

INTERFEROMETRIJSKI SONAR U NELINEARNOJ AKUSTICI, sa predajnim pretvaračima (SA, SB) medjusobno razmaknutim na rastojanju znatno većem od sopstvene širine, nazn ačen time, što su oba, istovremeno visokofrekventnim signalima napajana pretvarača (SA, SB) predajne antene (A) povezana sa generatorom (11), pri čemu su generator (11) i pretvarači (SA, SB) medjusobno spojeni pojačivačima (10A, 10B) signala, što je postavljeno kolo (20) za pomeranje faze sa unapred zadatom frekvencijom, spojeno sa pojačivačem (10B), što su u prijemnoj anteni (B) medjusobno spojeni hidrofoni (3.1, 3.2,... 3.i, 3.i+1,...3N-1,3.N) pri čemu su pojačivači (30.1,30.2,...30.i,30.i+1) niskofrekventnih signala spojeni sa kolom (31) za formiranje paralelnih multipleksiranih kanala (B1,B2,...Bk, ...B2m-1) usmerenih na kolo (32) za detekciju spojeno sa jedinicom (33) za vizuelno prikazivanje. Prijava sadrži još 1 patentni zahtev.
