Abstract. In this paper, we introduce a type of weighted multilinear Hardy operators and obtain their sharp bounds on the product of Lebesgue spaces and central Morrey spaces. In addition, we obtain sufficient and necessary conditions of the weight functions so that the commutators of the weighted multilinear Hardy operators (with symbols in central BMO space) are bounded on the product of central Morrey spaces. These results are further used to prove sharp estimates of some inequalities due to Riemann-Liouville and Weyl.
In order to track the moving target precisely on the airport surface, the Variable Structure Interacting Multiple Model Algorithm (VS-IMM) is applied to realize the Surface Movement Radar (SMR) tracking of target. Firstly, according to the actual movement of aircraft, the paper establishes a constant acceleration motion model, constant turn motion model and constant velocity motion model. Then, the VS-IMM algorithm is applied to the airport surface movement target tracking. Finally, VS-IMM is compared with IMM. Simulation results show that VS-IMM algorithm is more reliable than IMM algorithm on tracking of moving target on airport surface
