Accuracy analysis and improvement of different Alpha-Beta filtering algorithms

Maneuvering target tracking is an important part of radar application system, target tracking accuracy is regarded as an important index when evaluating an algorithm''s performance for the maneuvering target tracking,it is the focus of attention of most people. The characteristics were summarized through the analysis and comparison of four traditional Alpha-Beta filtering algorithms, and according to these characteristics, an Adaptive alpha-beta filter algorithm was obtained by improving traditional algorithms. Compared with the traditional Alpha-Beta filtering algorithm, the Adaptive Alpha-Beta filter algorithm is best in overall filtering results, and also has the highest accuracy.
