    Constant false alarm rate (CFAR) detection is a common form of adaptive algorithm used in radar systems to detect target returns against a background of noise, clutter and interference. [ 1 ] Principle

  3. CIFAR-10 - Wikipedia

    en.wikipedia.org/wiki/CIFAR-10

    CIFAR-10 is a set of images that can be used to teach a computer how to recognize objects. Since the images in CIFAR-10 are low-resolution (32x32), this dataset can allow researchers to quickly try different algorithms to see what works. CIFAR-10 is a labeled subset of the 80 Million Tiny Images dataset from 2008, published in 2009. When the ...

    This takes place before Doppler CFAR detection processing. A large modulation index is needed for practical reasons. A large modulation index is needed for practical reasons. Practical systems introduce reverse FM on the receive signal using digital signal processing before the fast Fourier transform process is used to produce the spectrum.

  5. Automatic target recognition - Wikipedia

    en.wikipedia.org/wiki/Automatic_target_recognition

    Automatic target recognition (ATR) is the ability for an algorithm or device to recognize targets or other objects based on data obtained from sensors.. Target recognition was initially done by using an audible representation of the received signal, where a trained operator who would decipher that sound to classify the target illuminated by the radar.

  9. Passive radar - Wikipedia

    en.wikipedia.org/wiki/Passive_radar

    The concept of passive radar detection using reflected ambient radio signals emanating from a distant transmitter is not new. The first radar experiments in the United Kingdom in 1935 by Robert Watson-Watt demonstrated the principle of radar by detecting a Handley Page Heyford bomber at a distance of 12 km using the BBC shortwave transmitter at Daventry.
