ABSTRACT:
A doubly adapative constant false alarm rate (CFAR) apparatus utilizing a doubly adaptive detector which is based upon the use of an auxiliary parallel adaptive detector in addition to the conventional main adaptive detector. The auxiliary adaptive detector has a lower threshold setting. The threshold crossing rate of the auxiliary detector, which depends upon the clutter statistics, is used to adjust the base multiplier setting of the main detector.
