Abstract

The seas, which covers approximately 2/3 of our world, contain many living species as well as many human-made structures. Today, passive acoustic listening in underwater environment is used in many applications such as detection/positioning of leaks in underwater pipelines, detection of ships, monitoring of marine animals. Another acoustic source that can be detected with these already installed systems is aircraft. The acoustic sound levels produced by aircraft flying at certain distances above the sea are at a level that cannot be neglected. In addition, the amplitude of the sound pressure doubles as the sound signal passes from the air environment to the water environment. This allows aircraft to be detected more easily under water. Thus, aircraft that violate the borders of other countries over the sea without permission can be detected and located. In this study, an investigation was made on the detection distances of four different aircraft, a helicopter (Bell 212) and three various fixed wing propeller aircraft (B-N Islander, Twin Otter, P-3 Orion) from underwater. Thus, a preliminary study has been made for an aircraft positioning system that can be used in the underwater environment.

Özet

Dünyamızın yaklaşık 2/3’ünü kaplayan denizler birçok canlı türünü içinde barındığı gibi insan yapımı olan birçok yapıyı da içinde ve üstünde taşımaktadır. Günümüzde sualtı ortamında pasif akustik dinleme sualtı boru hatlarındaki sızıntıların algılanması/konumlandırılması, gemilerin algılanması, deniz canlılarının takip edilmesi gibi birçok uygulamada kullanılmaktadır. Zaten kurulu olan bu sistemlerde algılanabilecek başka bir akustik kaynak ise hava taşıtlarıdır. Denizin üstünde belirli mesafelerde uçan hava taşıtlarının ürettikleri akustik ses seviyeleri ihmal edilemeyecek düzeylerdedir. Ayrıca ses sinyali hava ortamından su ortamına geçerken ses basıncının genliği ikiye katlanmaktadır. Bu durum da hava taşıtlarının suyun altından daha kolay algılanabilmelerine izin vermektedir. Böylece izinsiz olarak başka ülkelerin sınırlarını deniz üstünden ihlal eden hava taşıtları algılanıp konumlandırılabilir. Bu çalışmada bir helikopter (Bell 212) ve üç farklı sabit kanatlı pervaneli uçak (B-N Islander, Twin Otter, P-3 Orion) olmak üzere dört farklı hava taşıtının sualtından algılanma mesafeleri hakkında bir inceleme yapılmıştır. Böylece denizaltı ortamında kullanılabilecek bir hava taşıtı konumlandırma sistemi için bir ön çalışma yapılmıştır.
