Distributed clutter
WebApr 1, 2016 · In the case where the clutter measurements are homogeneous and independent Exponentially distributed returns, a detection process such as that illustrated in Fig. 1, can achieve the CFAR property for a very large class of admissible clutter measurement functions f 1, f 2 and g (f 1, f 2).The selection of alternatives to the … WebFinally, surface clutter is distributed in Doppler as a result of platform motion. There are two options available to designate regions of the surface for clutter generation. The first is automatic mainlobe clutter, which generates clutter inside the footprint of the mainlobe of the radar antenna. This is only possible when the radar being used ...

In this case, a changing threshold can be used, where the threshold level is raised and lowered to maintain a constant probability of false alarm. This is known as constant false alarm rate (CFAR) detection.
