İnce Düzlemlerde Yayılan Ultrason Dalgası Kullanılarak Hedef Uzaklığının Kestirilmesi

Yıl 2017, Cilt: 10 Sayı: 1, 138 - 147, 28.06.2017

Elastik dalgalar, sadece gaz ve
sıvılarda değil aynı zamanda katılarda da yayılırlar. Katılar, sıvı ve gazlarda
olmayan form elastisitesine sahip olduğundan, katıların elastik özellikleri
farklıdır. Bu nedenle, sadece boylamsal dalgalar değil aynı zamanda diğer
dalgalar da katılarda yayılabilir. Katı içinde yayılan dalgalar kullanılarak
hedefin konumu hakkında bilgi edinilebilir. Bu çalışmada ince düzlemlerde tek
transdüktör kullanılarak ultrasonik dalga yayılımının modellenmesi yapılarak,
uyarlamalı algoritma ile hedef uzaklığı kestirilmektedir. Elde edilen
sonuçlarda, modellenen dalga yayılımında ultrasonik dalganın hızı ile birlikte
zaman gecikmesi uyartım noktasının sensöre olan uzaklığı ile ilintili olduğu
için, uyarlamalı algoritma ile darbe cevabı başlangıç noktası belirlenerek
hedef konumunun tespit edilebildiği görülmektedir.

Estimation of Target Distance by Using Propagating Ultrasound Wave in Thin Plates

Elastic
waves propagate not only in gases and liquids but also in solids. The elastic
properties of solids are different since they have form elasticity which
liquids and gases don’t have. Because of this reason, not only longitudinal
waves but also other waves can propagate in solids. Waves propagating in solids
can be used to get information about target location. In this paper, modelling
of ultrasonic wave propagation in thin plates is investigated by using a single
transducer and target distance is estimated with adaptive algorithm. According
to the obtained results, it can be seen that target location can be estimated
by detecting the starting point of the impulse response with adaptive algorithm
since the delay along with the velocity of ultrasound wave in the modelled wave
propagation is related to the distance between the excitation point and sensor
