  This letter addresses the detection problem of dim maneuvering targets in the
presence of range cell migration. Specifically, it is assumed that the moving
target can appear in more than one range cell within the transmitted pulse
train. Then, the Bayesian information criterion and the generalized likelihood
ratio test design procedure are jointly exploited to come up with six adaptive
decision schemes capable of estimating the range indices related to the target
migration. The computational complexity of the proposed detectors is also
studied and suitably reduced. Simulation results show the effectiveness of the
newly proposed solutions also for a limited set of training data and in
comparison with suitable counterparts.
