Adaptive Radar Detection of Dim Moving Targets in Presence of Range Migration

This letter addresses adaptive radar detection of dim moving targets. To circumvent range migration, the detection problem is formulated as a multiple hypothesis test and solved applying model order selection rules which allow to estimate the “position” of the target within the CPI and eventually detect it. The performance analysis shows that the newly proposed architectures can provide an accurate estimate of the target position along with improved detection performance with respect to existing competitors.
