  2. Pulse-repetition frequency - Wikipedia

    en.wikipedia.org/wiki/Pulse-repetition_frequency

    Doppler signals fall between 1.5 kHz, and 15 kHz, which is audible, so audio signals from medium-PRF radar systems can be used for passive target classification. For example, an L band radar system using a PRF of 10 kHz with a duty cycle of 3.3% can identify true range to a distance of 450 km (30 * C / 10,000 km/s).

  3. AN/MPQ-64 Sentinel - Wikipedia

    en.wikipedia.org/wiki/AN/MPQ-64_Sentinel

    The AN/MPQ-64 Sentinel is an X-band electronically steered pulse-Doppler 3D radar system used to alert and cue Short Range Air Defense (SHORAD) weapons to the locations of hostile targets approaching their front line forces. It is currently produced by Raytheon Missiles & Defense.

    en.wikipedia.org/wiki/AN/AWG-9

    The AN/AWG-9 and AN/APG-71 radars are all-weather, multi-mode X band pulse-Doppler radar systems used in the F-14 Tomcat, and also tested on TA-3B. [1] It is a long-range air-to-air system capable of guiding several AIM-54 Phoenix or AIM-120 AMRAAM missiles simultaneously, using its track while scan mode.

  5. Volumetric Imaging and Processing of Integrated Radar

    en.wikipedia.org/wiki/Volumetric_Imaging_and...

    Volumetric Imaging and Processing of Integrated Radar, known by the acronym VIPIR, is an analysis and display program for Doppler weather radar, created and sold by Baron Services. [1] This software allows improved analysis of radar data for private users, in particular television stations, similar to the Weather Decision Support System program ...

  6. AN/APG-65 radar family - Wikipedia

    en.wikipedia.org/wiki/AN/APG-65_radar_family

    The APG-73 is a late 1980s "upgrade of the APG-65 that provides higher throughputs, greater memory capacity, improved reliability, and easier maintenance". [1] To reduce production costs, many of the upgraded radar's modules are common with the APG-70 (F-15E Strike Eagle) radar; its software engineers chose the JOVIAL programming language so that they could borrow and adapt existing software ...

  7. Pulse-Doppler radar - Wikipedia

    en.wikipedia.org/wiki/Pulse-Doppler_radar

    A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity.

  9. Range ambiguity resolution - Wikipedia

    en.wikipedia.org/wiki/Range_ambiguity_resolution

    This signal processing technique is required with pulse-Doppler radar. [ 1 ] [ 2 ] [ 3 ] The raw return signal from a reflection will appear to be arriving from a distance less than the true range of the reflection when the wavelength of the pulse repetition frequency (PRF) is less than the range of the reflection.
