Abstract:

Due to the current maneuvering target model is developing towards more and more modular and parallel computing, which puts forward higher requirements for calculation efficiency of the algorithm. For high supersonic maneuvering targets in near space, their maneuvering forms are very complex, since the precision of a single target maneuvering model cannot satisfy the requirements of tracking. So it is necessary to use the interactive multiple model algorithm for cross coupling based on a variety of models. The characteristic of this algorithm is adapted to that of high speed and high maneuver for near space targets. This paper puts forward an algorithm called adaptive grid interacting multiple model algorithm which is used to track high supersonic maneuvering targets in near space, this algorithm guarantees large target tracking accuracy and calculation efficiency, the validity of the algorithm is verified with numerical simulation results.
