What is A-scope
It is a two dimensional Radar display. The horizontal and vertical coordinates represent the azimuth angle and the range of the target respectively. It is more suitable for military Radars.
It is a two-dimensional Radar display. The horizontal and vertical coordinates represent the azimuth angle and elevation angle respectively.Here, intensity modulation takes place.
It is a two dimensional Radar display. The horizontal and vertical coordinates represent the range and echo amplitude of the target respectively. It is more suitable for manually tracking Radar.
What is B-scope
It is a two dimensional Radar display. The horizontal and vertical coordinates represent the range and echo amplitude of the target respectively. It is more suitable for manually tracking Radar.

What is C-scope
It is a two dimensional Radar display. The horizontal and vertical coordinates represent the azimuth angle and the range of the target respectively. It is more suitable for military Radars.
It is a two-dimensional Radar display. The horizontal and vertical coordinates represent the azimuth angle and elevation angle respectively. Here, intensity modulation takes place. Usually synthetic video

D-Scope
Elevation vs. Range similar to a B-scope, with elevation replacing
If the electron beam is deflected or the intensity-modulated spot appears on the Radar display due to the presence of target, then it is known as blip. C-Scope becomes D-Scope, when the blips extend vertically in order to provide the distance.
It is more suitable for military Radars.
What is E -scope
It is the modified version of A-Scope. It displays the target as radial deflection from time base.
Elevation vs. Range similar to a B-scope, with elevation replacing
It is the modified version of C-Scope. It displays the target as radial deflection from time base.
Plan position indicator (PPI)
PPI is like A scope radar display
PPI is a type of radar display that represents the radar antenna in the center of the display, with distance and height above ground drawn as concentric circles. As the radar antenna rotates, a radial trace on the PPI sweeps in unison with it about the center point. It is the most common type of radar display.
It is the modified version of B-Scope in order to provide the information about elevation angle of the target. It displays the target as two blips, which are closely spaced. This can be approximated to a short bright line and the slope of this line will be proportional to the sine of the elevation angle.
Range-Height Indicator or RHI display.
It is a Radar display, which uses intensity modulation. The horizontal and vertical coordinates represent the range and height of the target respectively.
