    Radar display - Wikipedia

    • A radar display is an electronic device that presents radar data to the operator. The radar system transmits pulses or continuous waves of electromagnetic radiation, a small portion of which backscatter off targets (intended or otherwise) and return to the radar system. The receiver converts all received electromagnetic radiation into a continuous electronic … 展开

    Oscilloscopes

    Early radar displays used adapted oscilloscopes with various inputs. An oscilloscope generally receives three channels of varying (or oscillating) voltage as input and displays this information on a cathode ray tube. … 展开

    A-Scope

    The original radar display, the A-scope or A-display, shows only the range, not the direction, to targets. These are sometimes referred to as R-scopes for range scope. A-scopes were used on the earliest radar systems during … 展开

    B-Scope

    A B-scope or b-scan provides a 2-D "top down" representation of space, with the vertical axis typically representing range and the horizontal axis azimuth (angle). The B-scope's display represented a horizontal "slice… 展开

    Why were radar displays difficult to produce?
    Early in radar development, however, numerous circumstances made such displays difficult to produce. People developed several different display types. Oscilloscope attached to two sine-wave voltage sources, producing a circle pattern on the display. Early radar displays used adapted oscilloscopes with various inputs.
