The aerodynamic characteristics needed for the motion model are identified by using artificially generated trajectory of projectile that imitates the flight path recorded by the 3D Doppler radar. The trajectories of 35 mm TP-T projectile were generated using the motion model with 6 degrees of freedom (6DoF model) with the aerodynamic coefficients produced by PRODAS software. The identification process was conducted for the explicit form of the modified point-mass trajectory model. The main goal of the presented work is to obtain valid tool for aerodynamic coefficients identification based on real data (e.g. recorded trajectory, meteorological data) gathered during field tests. It is essential to determine the number of measurements made by radar during the projectile’s flight that is necessary for the identification process to be conducted correctly. Authors present some of the results of the simulation tests - identified coefficients and errors (relative and absolute) between the original trajectories and the trajectories generated with the identified model.
