1. A method of determining kinetic information of a moving vehicle, the method comprising:
receiving, using a radar device provided in the moving vehicle, signals reflected by a plurality of objects;
obtaining a plurality of candidate kinetic information to the moving vehicle based on the signals reflected by the plurality of objects;
estimating, through spatial filtering, current first kinetic information related to the moving vehicle from signals reflected by one or more stationary objects; and
predicting, using a kinetic model, the current first kinetic information related to the moving vehicle based on previous first kinetic information related to the moving vehicle; and
correcting the estimated current first kinetic information based on the predicted current first kinetic information.
