1. A method to calibrate a resistivity logging tool, comprising:
disposing the resistivity logging tool into a formation, wherein the resistivity logging tool comprises a transmitter and a receiver;
transmitting a signal with the transmitter;
acquiring a return signal at each logging point with the receiver;
assuming a formation model for a first set of continuous logging points in the formation;
assigning at least one calibration coefficient to each type of signal;
building an unknown vector that includes unknown model parameters and the calibration coefficients; and
inverting the unknown vector that includes the calibration coefficients and the unknown model parameters of the formation model, to calibrate the resistivity logging tool.
