  2. Radar jamming and deception - Wikipedia

    en.wikipedia.org/wiki/Radar_jamming_and_deception

    This technique can change the range the radar detects by changing the delay in transmission of pulses, the velocity the radar detects by changing the Doppler shift of the transmitted signal, or the angle to the plane by using AM techniques to transmit into the sidelobes of the radar. Electronics, radio equipment, and antenna can cause DRFM ...

  3. Digital radio frequency memory - Wikipedia

    en.wikipedia.org/wiki/Digital_radio_frequency_memory

    Since a DRFM system is designed to create a false target to a radar system, this technology can be employed to perform hardware-in-the-loop simulation. [1] [2] Hardware-in-the-loop simulation is an aid to the development of new radar systems, which allows for testing and evaluation of the radar system earlier in the design cycle. This type of ...

  4. 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.

  5. Radar - Wikipedia

    en.wikipedia.org/wiki/Radar

    Radar systems must overcome unwanted signals in order to focus on the targets of interest. These unwanted signals may originate from internal and external sources, both passive and active. The ability of the radar system to overcome these unwanted signals defines its signal-to-noise ratio (SNR). SNR is defined as the ratio of the signal power ...

  6. Pulse-Doppler radar - Wikipedia

    en.wikipedia.org/wiki/Pulse-Doppler_radar

    The Hughes AN/ASG-18 Fire Control System was a prototype airborne radar/combination system for the planned North American XF-108 Rapier interceptor aircraft for the United States Air Force, and later for the Lockheed YF-12. The US's first pulse-Doppler radar, [4] the system had look-down/shoot-down capability and could track one target at a time.

  7. Radar warning receiver - Wikipedia

    en.wikipedia.org/wiki/Radar_warning_receiver

    Radar warning receiver (RWR) systems detect the radio emissions of radar systems. Their primary purpose is to issue a warning when a radar signal that might be a threat is detected, like a fighter aircraft's fire control radar. The warning can then be used, manually or automatically, to evade the detected threat.

  8. Radar engineering - Wikipedia

    en.wikipedia.org/wiki/Radar_engineering

    Radar engineering is the design of technical aspects pertaining to the components of a radar and their ability to detect the return energy from moving scatterers — determining an object's position or obstruction in the environment.
