“…The most famous and widespread devices are VLF (very low frequency detectors) and PI (pulse induction) type metal detectors. The first is based on the transmission/reception of a tone signal, whereas the second works using pulse signals [9, 20]. It should be said that these devices are designed to detect hidden metal objects, and in most cases they successfully perform their task.…”

“…However, there are practically no devices that allow identifying the composition of a metal object with eddy current devices. In most cases, they allow a dichotomous analysis of the object (the object is made of ferrous or non-ferrous metal) [9,10]. Among the eddy current devices, it is possible to single out the developed eddy current radio technical system (RTS) [11,12], the basis of which is the assessment of phase shifts that occur during probing of metal objects with a low-frequency electromagnetic field [13,14].…”

“…На сьогодні для вирішення цієї задачі використовуються різні методи [1,2]. Найбільш розповсюдженими серед них є методи, які основані на проведені хімічних, оптико-емісійних та рентгено-флуоресцентних аналізах [3,4].…”

“…The latter operate with pulsed signals. They are inherently low frequency radio location stations [4]. In the modern market, ECD are represented by metal detectors, produced by companies Minelab, Fisher, Garret, AKA [5].…”
