Abstract :
Strictly speaking, all the systems which are used in the field of target tracking are nonlinear and non-Gaussian. The shadowing filter algorithm and its realization methods which include gradient descent of indeterminism and Iterative gradient descent of indeterminism are discussed in this paper. And compare with EKF at tracking precision, the simulation shows that the performance of shadowing filter is superior to that of EKF.
