Embodiment Construction
[0051] The present invention will be further described below in conjunction with the accompanying drawings.
[0052] refer to Figure 1 to Figure 4 , a target tracking method based on distributed matrix weighted fusion Gaussian filtering, the method includes the following steps:
[0053] Step 1: Establish the state space model and measurement model of the nonlinear system, the process is as follows:
[0054] 1.1 Establish a system state model
[0055] x k+1 =f(x k )+w k (1)
[0056] where x k is the system state at time k, f(x k )∈R n is any nonlinear vector function, w k For the covariance is Q k Gaussian white noise;
[0057] 1.2 Establish system measurement model
[0058]
[0059] where i is the number of the observation station, is the measurement value of the i-th observation station at time k+1, is any nonlinear vector function, is the covariance of Gaussian white noise;
[0060] Step 2: Calculate local Gaussian filter estimation and covariance, ...
