Performance analysis of Nitzberg's clutter map for Weibull distribution

The clutter map analyzed by Nitzberg, which averages the detector outputs of the same resolution cell over several past scans to set the detection threshold, plays an important role in radar detection fields. In this work, the average detection threshold (ADT) of Nitzberg's clutter map is derived and its steady-state property is analyzed, moreover, the detection performance of Nitzberg's clutter map for Weibull background is analyzed by the importance sampling technique.
