  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. Radar display - Wikipedia

    en.wikipedia.org/wiki/Radar_display

    The offset is created by dividing the radio signal into two, then slightly delaying one of the signals so it appears offset on the display. The angle was adjusted by delaying the time of the signal via a delay, the length of the delay being controlled by a voltage varying with the vertical position of the antenna. This sort of elevation display ...

  4. Broadcast delay - Wikipedia

    en.wikipedia.org/wiki/Broadcast_delay

    As a result, until today, many live programs, such as music and talent competition shows, are usually tape delayed for the western half of the country and aired as-live (although they may include edits to streamline the broadcast or resolve technical faults). Australian network television schedule is largely patterned from the U.S. format.

  5. Zap time - Wikipedia

    en.wikipedia.org/wiki/Zap_time

    Availability of the channel (channel replication point) Network factors tend to make up only a small portion of the overall delay, between 50 and 200ms of the overall zap time. Network quality of service (QoS) can reduce these time to minimize jitter , latency, and packet drop.

  6. Round-trip delay - Wikipedia

    en.wikipedia.org/wiki/Round-trip_delay

    In telecommunications, round-trip delay (RTD) or round-trip time (RTT) is the amount of time it takes for a signal to be sent plus the amount of time it takes for acknowledgement of that signal having been received. This time delay includes propagation times for the paths between the two communication endpoints. [1]

  7. Shapiro time delay - Wikipedia

    en.wikipedia.org/wiki/Shapiro_time_delay

    The Shapiro time delay effect, or gravitational time delay effect, is one of the four classic Solar System tests of general relativity. Radar signals passing near a massive object take slightly longer to travel to a target and longer to return than they would if the mass of the object were not present.

  8. Weather radar - Wikipedia

    en.wikipedia.org/wiki/Weather_radar

    Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).

  9. Power delay profile - Wikipedia

    en.wikipedia.org/wiki/Power_delay_profile

    The power delay profile (PDP) gives the intensity of a signal received through a multipath channel as a function of time delay. The time delay is the difference in travel time between multipath arrivals. The abscissa is in units of time and the ordinate is usually in decibels.
