  • Abstract
    Search radars require a constant false alarm rate (CFAR) receiver to compensate for changes in noise and clutter levels. A CFAR circuit is described which uses matched dispersive delay lines flanking a hard limiter. The circuit´s operation is discussed and plan-position indicator (PPI) photographs are shown which illustrate its effectiveness.
