A kangako ukuba ukhethe njani sounder ukuloba

Namhlanje, izincedisi okuloba zobugcisa usabonisa kwinqanaba elitsha. Akukho namnye kumangaliswa ngentonga carbon lula eyothusayo, ngokunjalo coil obuphuma Thokoza kuyo. Kwaye ke kudala "ezisemagqabini" isixhobo ukukhangela isitokhwe iintlanzi emanzini kwaye bahlole emazantsi isakhiwo, njengoko sounder, ngokuya kwanda ngakumbi phakathi Abalobi.

Noko ke, asinguye wonke umntu uyazi ukuba ukhethe njani sounder ukuloba, nto leyo iluncedo kakhulu ukuba uhlobo oluthile lokuloba. Uluhlu zezi zixhobo likhulu kakhulu, ngoko nkqu Angler onobuchule akukho lula ukukhetha.

Kuba uvandlakanyo yamacebo kufuneka azi kumthetho sonar. Enyanisweni, ifowuni iqulathe iinxalenye ezimbini: samaza-umyalezo (likhupha kwaye esifumana i SIGILL uphawu cuke yabonisa kuyo sele intlanzi kunye ezantsi emanzini), kunye kumqhubekekisi kwiinkqubo idata ezifunyenweyo kwaye kukukhupha kuyo igama lomzobo kwikhusi.

sonar Modern uyakwazi ukubona yoncedo ezantsi, ubukho intlanzi kunye nobunzulu apho lujolise okwangoku, ubunzulu inkoliso dama, kwaye eyiyona ukuqikelela ubungakanani eziphilileyo ezidadayo kunye izinto ezahlukeneyo. imifuziselo abaninzi umsebenzi kelelo, ukuvumela ukuba hlola kwindawo ethile indawo lwamanzi iinkcukacha ezingaphezulu.

Ukuze uphendule umbuzo ukuba ukhethe njani sounder ukuloba, kufuneka bazi ukuba yintoni umahluko ophambili phakathi imifanekiso. Ngoko ke, lo izixhobo ezibiza imali zixhotyiswe nge beam enye kuphela elitsolo ekujongeni ukuba ubandakanya zonke degrees 9-24. Ukunyusa ukusebenza kula fishfinders hayi enikiweyo. Ngenxa-beam "nale intlanzi" makhe kakuhle ngokwaneleyo ukuze abone uncedo ezantsi, kodwa ngenxa kwindawo emxinwa amanyathelo olungasebenziyo zikhangela ntlanzi.

Sicinga ukuba ukhethe njani sounder ukuloba, kufanele kuqatshelwe ukuba iinguqulelo sonar zibiza kakhulu ukuba isixhobo zazo 2 (okanye 3) loMthetho umqadi zokuhlola, nto leyo ndawo uphendlo kwi kubunzulu weemitha ezili-10 kwiyunithi degree-45 ifikelela 8.5 m kunye nezinga 90 - 20. Ngo-izixhobo ezinjalo inika amandla ukudibanisa ezininzi kuThixo boluvo ezongezelelweyo.

imifuziselo Okuninzi nabizayo-ntathu, nanzo ebekwe kwiskrini indawo yezinto zasemanzini isiqabu ezantsi ngokohlobo umfanekiso-ntathu. Ngoncedo lwabo, umlobi ngokulula ukubona indawo intlanzi (zombini ulwalathiso umgama indawo kwindawo yayo).

Ekugqibeleni, ezibiza kakhulu kwaye olusebenzayo abalindi-art sonars Interphase, nee-iseti elide zokuva kunye umboniso umbala omkhulu.

Ezifana device ngakumbi luncedo zhestkokorpusnyh abanini lwezikhephe, baya kukunceda ukuba uphephe zicinywe kwamanzi izinto.

Ngoko ke, umbuzo ukuba ukhethe njani sounder ukuloba, kuxhomekeke kudidi lwe okuloba kwaye zinxulumene ngokusondeleyo amathuba zemali. A ukhetho, njengokuba ubona, libanzi kakhulu. Umzekelo, sounders ukuloba ukusuka elunxwemeni akukho mfuneko yokuba side sibe namandla kakhulu, kuba uya kusetyenziswa nobunzulu hayi kakhulu. Ngoko ke, enoba okanye ukuba ahlawule?

Phakathi abalobi Russian kukho sounders echo zithandwa "gqirha" kweendidi ngeendidi.
