Abstract

The invention discloses a trajectory initiation method for a three-dimensional space turning maneuvering target, and relates to the technical field of multi-sensor information fusion. Through coordinate transformation, trajectory detection, state and error covariance estimation, and coordinate inverse transformation, a target exists in the observation space is finally detected and the state estimation of the target is obtained. The invention further discloses a trajectory initiation device for the three-dimensional space turning maneuvering target, the problem that the trajectory of the three-dimensional space turning maneuvering target is difficult to start is effectively solved. The trajectory initiation method and device for the three-dimensional space turning maneuvering target can beused in the field of multi-target tracking and has strong practicability.

Description

technical field [0001] The invention belongs to the technical field of multi-sensor information fusion, and in particular relates to a trajectory initiation method and device for a turning maneuvering target in three-dimensional space. Background technique [0002] With the development of science and technology, the detection of new targets in the observation space is more and more involved in the field of automatic control and multi-sensor information fusion technology, and the trajectory initiation is the key research content of researchers in this field. [0003] The main task of trajectory initiation is to detect a new object appearing in the observation space and initiate its trajectory using the measurements obtained by the sensor at many different times. At present, the commonly used trajectory initiation methods are usually suitable for trajectory initiation when the target is assumed to be moving at a constant speed or uniform acceleration, but these existing trajec...
