Embodiment Construction
[0064] The present invention mainly adopts the method of computer simulation to verify, and all steps and conclusions are verified correctly on MATLAB-R2010b. The specific implementation steps are as follows:
[0065] Step 1. Input the track and calculate the predicted value at time k:
[0066] Consider a uniform linear moving target in the Cartesian coordinate system, the initial state of the target is X(0)=[80m, 6m / s, 100m, 0m / s], and the first two frames of the track have started. The specific parameter settings are shown in Table 1 and Table 2. At time k, the predicted state value X(k|k-1) of the target is obtained: X(k|k-1)=FX(k-1), and the covariance one-step predicted value P(k|k-1): P(k|k-1)=FP(k-1)F T +Q.
