Abstract. In looking radar systems
using automatic target detection, selection fluctuating small-sized targets (FST)
on the background clutter is a rather complicated task. We propose a
probabilistic model of the radar channel difference vector processing observations
polarimetric synthetic aperture radar (PolSAR), which will guarantee to detect
fluctuating on polarization featured small-sized target to fluctuating background
clutter. It is shown that among all possible FST can extract two specific (singular)
purpose – maximum visible and most hidden in the clutter, which generally increases
the efficiency of detection of small-sized targets.
Keywords: detection of targets,
the fluctuating small-sized target, polarimetric SAR.
