Abstract

An improved design software-based replica
correlator method within the microprocessor-controlled sonar buoy systems has
been proposed which improved the performance of detecting objects underwater. In
the sea or ocean, the microprocessor-controlled buoy is provided to be
automatically wirelessly scan for removal of underwater information and
transmit it wirelessly to the main control station for additional processing
and ultimate decision. In this study, sonar buoy performance and system design
proposal with 7-31 cell replica correlation are presented. Although the digital
delay lines are used to minimize the complexity of hardware-based replica
correlator, the proposed software replica-correlated system within
microprocessor-controlled buoys, has improved the performance.

Sualtı Nesnelerinin Gözetimini Gerçekleştiren Mikroişlemci Kontrollü Sonar Şamandıra Performansını Artırmak İçin Algoritma Tasarımı

Abstract

Sualtında bulunan nesneleri gözetlemek amacıyla
uygulanan mikroişlemci kontrollü sonar şamandıra sistemlerinin performansı için
geliştirilmiş bir tasarım yaklaşımı önerilmiştir. Denize veya okyanus
içerisinde, mikroişlemci kontrollü şamandıra, sualtı bilgisinin çıkarılması
için otomatik olarak taranması ve daha ileri işlem ve nihai kontrol eylemi
sağlanması amacıyla bir uzak yer istasyonuna kablosuz olarak iletilmesi
sağlanır. Bu çalışmada, 7-31 hücre replika korelasyonunu içeren sonar şamandıra
performansı ve sistem tasarım taslağı sunulmuştur. Donanımsal replika
korelatörünün karmaşıklığı, dijital gecikme kanalları kullanılarak en aza
indirilmesine rağmen, önerilen mikroişlemci kontrollü şamandıra, yazılım
aracılığıyla replika korelasyonu gerçekleştirilmiş ve geliştirilmiş sistemle
performans artırılmıştır.
