    en.wikipedia.org/wiki/YLC-2_Radar

    In the mid-2000s, an improved version labeled YLC-2A was deployed to the PLA. Equipped with a new Giga-flops digital signal processor, it is capable of Digital Moving Target Indication (DMTI) and Constant false alarm rate (CFAR) processing. An S-band variation called YLC-2U with similar capabilities was also developed for SAM guidance.

    Detection using constant false alarm rate (CFAR) scheme; Association and tracking of object returns in range/Doppler space, known as "line tracking" Association and fusion of line tracks from each transmitter to form the final estimate of an object's location, heading and speed. These are described in greater detail in the sections below.

  5. Radar signal characteristics - Wikipedia

    en.wikipedia.org/wiki/Radar_signal_characteristics

    Constant False Alarm Rate, a form of Automatic Gain Control (AGC), is a method that relies on clutter returns far outnumbering echoes from targets of interest. The receiver's gain is automatically adjusted to maintain a constant level of overall visible clutter.

  6. Pulse-Doppler signal processing - Wikipedia

    Constant false alarm rate processing is used to examine each FFT output to detect signals. This is an adaptive process that adjusts automatically to background noise and environmental influences. There is a cell under test, where the surrounding cells are added together, multiplied by a constant, and used to establish a threshold.
