Problems solved by technology
[0002] Radar maneuvering target tracking is a difficult problem in the field of radar data processing, especially when two maneuvering targets meet, since the maneuvering characteristics of the two targets are random and unpredictable, there will be false correlation of radar tracks, resulting in The tracking error of the 2 maneuvering targets is large, and even the tracking target is lost
[0003] The application of the Singer model in maneuvering target tracking works well, because it fully considers the acceleration and deceleration characteristics of the target in radar target tracking, so the description of the real trajectory of the target is more accurate, but the current singer model tracking is mostly for a single target tracking, and when there are two maneuvering targets that meet, the tracking effect of the existing singer model is poor

The invention relates to a radar maneuvering intersection target tracking method based on a multi-hypothesis singer model. For the target in the intersection area, the multi-hypothesis singer model is used to track the junction target; S3, through the tracking of the multi-hypothesis singer model in step S2, accurate and stable tracking of the target is achieved. The advantages of the invention are: 1. It can reduce the tracking error in the tracking of the radar maneuvering intersection target and realize more accurate target tracking; 2. It can reduce the probability of wrong tracking in the radar maneuvering intersection target tracking, and realize the correctness of the intersection target. 3. The invention has a wide range of applications, has no special requirements for the parameters of the radar system, and is feasible to popularize.
Description
technical field [0001] The invention relates to a radar maneuvering intersection target tracking method based on a multi-hypothesis singer model, and relates to the field of radar. Background technique [0002] Radar maneuvering target tracking is a difficult problem in the field of radar data processing, especially when two maneuvering targets converge, since the maneuvering characteristics of the two targets are both random and unpredictable, the false correlation of the radar track will occur, resulting in the error of the radar track. The two maneuvering targets have large tracking errors, and even lose tracked targets. [0003] The application of the Singer model is better in the tracking of maneuvering targets. Because it fully considers the acceleration and deceleration characteristics of the target in radar target tracking, the description of the real trajectory of the target is more accurate. However, the current Singer model tracking is mostly for a single target. ...
