Abstract: A method, device, system, and storage medium for tracking a moving target are provided. The method uses three-dimensional radar observation data to construct a state vector and a motion model of the moving target, thereby to construct a state equation and an observation equation for achieving filtering and tracking within a linear Gaussian framework. The disclosure is also suitable for a moving target in a two-dimensional scene with a distance and an azimuth, and the disclosure use a two-dimensional observation vector to construct a dynamic system to achieving tracking of the moving target. The disclosure can be used in radar systems containing Doppler measurements, and tracking of moving targets can be implemented by performing dimension-expansion processing on observation equations.
