A decoupled adaptive tracking filter for real applications
Tae Kyung Sung, Jang Gyu Lee · IEEE Transactions on Aerospace and Electronic Systems · 1997
A decoupled adaptive tracking filter for maneuvering targets under nonlinear measurement environment is presented. A modified input estimation method is implemented in a line-of-sight Cartesian coordinate system. Since the proposed filter has a decoupled structure, computation is drastically reduced without degrading performance. Also, due to small cross-correlation between pseudomeasurement noises, accuracy of maneuver detection is improved.
