  2. Pulse width - Wikipedia

    en.wikipedia.org/wiki/Pulse_width

    The amount of energy that is returned to the radar receiver is a function of the peak energy of the pulse, the pulse width, and the pulse repetition frequency. Increasing the pulse width increases the amount of energy reflected off the target and thereby increases the range at which an object can be detected. Radars measure range based on the ...

  3. Pulse-repetition frequency - Wikipedia

    en.wikipedia.org/wiki/Pulse-repetition_frequency

    The pulse-repetition frequency (PRF) is the number of pulses of a repeating signal in a specific time unit. The term is used within a number of technical disciplines, notably radar. In radar, a radio signal of a particular carrier frequency is turned on and off; the term "frequency" refers to the carrier, while the PRF refers to the number of ...

  4. Range ambiguity resolution - Wikipedia

    en.wikipedia.org/wiki/Range_ambiguity_resolution

    Range ambiguity resolution is a technique used with medium pulse-repetition frequency (PRF) radar to obtain range information for distances that exceed the distance between transmit pulses. This signal processing technique is required with pulse-Doppler radar. [1] [2] [3]

    Brunsviga 15 Mechanical Calculator Original Odhner-Arithmos-Typ-5. Brunsviga is a calculating machine company whose history goes back to 1892 with devices upgrading from mechanical to electrical thereafter. The firm Grimme & Natalis that manufactured the machines changed their name to Brunsviga Maschinenwerke A.G. in 1927.

  6. Pulse (signal processing) - Wikipedia

    en.wikipedia.org/wiki/Pulse_(signal_processing)

    Examples of pulse shapes: (a) rectangular pulse, (b) cosine squared (raised cosine) pulse, (c) Dirac pulse, (d) sinc pulse, (e) Gaussian pulse. A pulse in signal processing is a rapid, transient change in the amplitude of a signal from a baseline value to a higher or lower value, followed by a rapid return to the baseline value. [1]

  7. Channel 6 radio stations in the United States - Wikipedia

    en.wikipedia.org/wiki/Channel_6_radio_stations...

    In 1945, TV channel 6 was assigned use of 82-88 MHz, [10] with the channel's audio located at a center frequency of 87.75 MHz. That same year the standard FM broadcasting band was reassigned to 80 channels from 88.1 to 105.9 MHz, which was soon expanded to 100 channels ending at 107.9 MHz (channels 201–300).

    Jamal Murray tops the list of guards to avoid at their current cost in 2024-25 fantasy basketball leagues amid concerns about his health ahead of the season.

  9. Atmospheric radiative transfer codes - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_radiative...

    The radiative transfer equation is a monochromatic equation to calculate radiance in a single layer of the Earth's atmosphere. To calculate the radiance for a spectral region with a finite width (e.g., to estimate the Earth's energy budget or simulate an instrument response), one has to integrate this over a band of frequencies (or wavelengths ...
