The EMA3100A Target Motion Simulator is used to generate motion modeling and target tracking data in 2D and 3D Cartesian and polar domains. Motion modeling can be performed using known functions, polynomials, velocity vectors, and acceleration vectors starting from a point and time. Paths can be combined and true motion, sensor measurements, and missing data can be modeled by applying random distributions over time. The trajectories of targets can be viewed as static plots or animated plots showing the position of targets over time.
