This paper addresses range-spread target detection in spherically invariant random vector clutter.The modified scatterer density dependent(MSDD)detector is introduced
and the analytic expression relating false alarm probability to detection threshold is deduced.MSDD need to estimate the number of scatterers
and its performance degradation gracefully when there is a mismatch.To improve the robustness of MSDD
a detector based on ordered data variability(ODV)is proposed.The results show that ODV-MSDD is robust for various target range extent
and its detection performance is improved when increasing the number of scatterers
sensors and spiky of the clutter.Compared with the MSDD
ODV-MSDD estimates the number of scatterers adaptively
and it can improve performance and robustness of detector effectively.
