Abstract

Bu çalışmada, yakın yüzey araştırmalarında yaygın olarak kullanılan düşey gradyometre yönteminde farklı manyetometre aralıkları seçiminin düşey manyetik gradyent verileri üzerindeki etkileri incelenmiştir. Karada yapılan arazi çalışmalarında kullanılan düşey gradyometrelerin birçoğu 0.5, 1 ve 1.5m alıcı aralıklarının seçimine izin vermektedir. Bu nedenle çalışma kapsamında, hem model hem de arazi çalışmaları için alıcı aralıkları 0.5, 1 ve 1.5m olarak seçilmiş ve karşılaştırmalar bu alıcı aralıkları kullanılarak yapılmıştır. Model çalışması için kullanışlı bir yakın yüzey modelinden hesaplanan kuramsal ve arazi çalışması için arkeolojik bir alanda toplanan düşey manyetik gradyent verileri kullanılmıştır. Günümüzde düşey gradyent ölçümlerinde geleneksel olarak 0.5m alıcı aralığı kullanılmaktadır. Model ve arazi çalışmalarından görüleceği üzere, belirtiye neden olan kaynakların fiziksel ve geometrik özelliklerinin önceden kestirilmesi durumunda ve gürültü etkileri göz önünde bulundurulduğunda farklı alıcı aralıkları seçiminin önemi ortaya çıkmaktadır

The Selection of Different Sensor Intervals in Vertical Magnetic Gradiometer Method

Abstract

In this study, the effects of selection of the different magnetometer separations in vertical gradiometer method that widely used in near surface studies on the vertical magnetic gradient data are investigated. Many vertical gradiometers that used in ground studies allow the selection of 0.5, 1 and 1.5m receiver separations. For this reason in the frame of the study, both in the modelling and field studies, the receiver separations are selected as 0.5, 1 and 1.5m and comparisons are done using these receiver separations. For the model study a theoretical dataset computed from a functional subsurface model and for the field study a real archaeological vertical magnetic gradient dataset were used. Traditionally, 0.5m receiver separation is used in the vertical gradient surveys in nowadays. As can be seen both in the modelling and field studies, the necessity and importance of the selection of different receiver separations are appeared in cases of the estimation of physical and geometric parameters of the magnetic sources that caused the anomaly and in cases of the consideration of the noise effects
