A method for making directional resistivity measurements includes sequentially transmitting first and second axial and transverse electromagnetic waves in a borehole and receiving substantially pure axial and transverse components of each of the transmitted waves. A composite ratio of the received components is computed and may be utilized as an indicator of various formation parameters. The invention advantageously provides for the acquisition of compensated directional resistivity measurements.
