PROCESS OF EXAMINATION OF LAYERS OF OBJECTS LYING UNDER SURFACE Russian patent published in 1998 - IPC

FIELD: radiolocation, study of undersurface layers of various objects. SUBSTANCE: radio pulse signal reflected from examined object is delayed by some time interval during which assemblage of factors of reflection from undersurface layer of examined object including n≥5 extreme points is formed. This delayed signal is used as measurement one and from formed assemblage of actual part of factors of reflection from undersurface layer of examined object only extreme points and frequencies corresponding to them are isolated. They are used to evaluate electrophysical parameters of undersurface layer of examined object. EFFECT: expanded application field by way of determination of electrophysical parameters of medium of undersurface layers of objects having unspecified nature. 7 dwg
