The aim of this thesis was to perform the drift chamber calibration andcharged particles 3d track reconstruction for the P349 antiproton polarizationexperiment. A dedicated procedures were designed, implemented and tested on theexperimental data for the the D1 drift chamber. The calibration consisted ofthe drift time offsets determination, estimation of the initial drift time -space relations by means of the homogeneous irradiation method and theiterative procedure for the time - space relations optimization. Calibrationcurves for all wire planes of the detector were determined. The obtaineduncertainties of the hit position reconstruction are in the range of 150 - 220$\rm \mu m$. Furthermore, based on the prepared 3d track reconstruction angulardistribution of tracks passing through the drift chamber were determined.
