WitrynaThe application of Bayesian ltering and smoothing in this study is restricted to the domain of air surveillance radar systems, which means that the sensor is typically providing measurements in nonlinear coordinates. And the process, i.e. the kinematics of the observed airborne object in this case, is typically best described by nonlinear models. Witryna2 lip 2024 · This method employs a motion behavior model set (MBMS), a motion behavior recognition algorithm, and an active switching estimation and fusion algorithm. First, a recognizable MBMS, which can capture all the motion behaviors of a gliding flight vehicle, is established.
