A method and apparatus for estimating at least one parameter of interest in an earth formation using a signal from a receiver where a quadrature component of a signal at a plurality of frequencies is used to estimate a misalignment angle between the receiver and a transmitter. The apparatus may include at least one receiver, at least one transmitter, and at least one processor configured to excite the transmitter and estimate the misalignment angle. The method may include acquiring data at a plurality of frequencies, estimating a misalignment angle, and estimating at least one parameter of interest using the misalignment angle. The method may include performing multi-frequency focusing on the signal received at each of the plurality of frequencies.
