Adaptive Thresholding and Automatic Detection

  • Carl R. BarrettJr.

Abstract

The requirement for radar systems that can detect the presence of targets within background environments that are more complex and less known than thermal noise and maintain a controlled false alarm rate leads to increased emphasis on adaptive threshold automatic detection circuits. Systems that use automatic detection circuits to maintain, ideally, a constant false alarm rate by generating estimates of the receiver output when targets (of interest) are not present are called constant false alarm rate (CFAR) systems.
