In practice, each sensor may have different observation dimension; that is to say, each sensor may make use of different model to observe the same target. In order to solve the above problem, by mapping among the state spaces, a nonequal dimension MAP estimate fusion algorithm between the output target estimate state and feedback is presented in this paper. Computer simulations show the effect of algorithm.
