Antenna compensation method using direct coupling wave in polarimetric borehole radar measurement

摘要

Crosshole borehole radar measurement is needed to compensate the antenna transfer functions in polarimetric single-hole radar measurement with combinations of a di- pole antenna and cylindrical conducting slot antenna. This paper presents a method to estimate the antenna transfer function from the single-hole measurement alone. A small dipole model in a homogeneous medium is used to approxi- mate the relationship between the direct coupling wave in the single-hole measurement and the direct wave in crosshole measurement(antenna transfer function).
