An extended Kalman filter target tracker for spatially resovled targets with dynamic signatures

摘要

An extended Kalman filter was developed by Maybeck and Mercier [1] to track unresolved or point targets whose spatial signature is the point spread function of the sensor. An extension of this filter which takes into account the target shape and its variations with aspect angle will be developed and should offer improvement in several areas: performance agaisnt structured clutter; Maybeck considered only a white noise background; the errors and computations associated with segmentation are eliminated.
