Bistatic MIMO radar space maneuvering target tracking method
2015
The invention discloses a bistatic MIMO radar space maneuvering target tracking method capable of realizing accurate estimation and prediction of motion parameters such as the three-dimensional position and speed of space maneuvering targets. According to the method, a bistatic MIMO radar uniform circular array system is applied to space maneuvering target tracking, based on bistatic MIMO radar uniform circular array angle Doppler frequency estimation and the target state space, a measuring equation is established in a measuring right angle coordinate system for emitting and receiving uniform circular arrays according to a function relation between measuring elements and target motion state variables. A current statistics model applicable to maneuvering target tracking is employed to establish a state equation for describing the evolution of target motion parameters with time, the unscented Kalman filter algorithm applicable to nonlinear state filtering is employed to estimate the target motion parameters in real time, the target motion parameters can be predicted, and the tracking of the space maneuvering target is realized.
