What type of radar display shows Amplitude over range?

The 'A' display, also known as the amplitude display, is specifically designed to represent the amplitude of radar returns as a function of range. In this type of display, the vertical axis typically represents the amplitude or strength of the reflected radar signals, while the horizontal axis represents the distance or range from the radar to the target. This allows for a visual interpretation of how signal strength varies as a function of distance, making it easier to identify targets based on their reflectivity.

This format is advantageous in various radar applications, including identifying the size and material composition of objects, as stronger radar returns often indicate larger or more reflective targets. The amplitude information can be crucial for tasks such as target classification and tracking.

In contrast, other types of displays, such as the 'B', 'C', or 'D' displays, might focus on different aspects of the radar data, such as velocity or range-Doppler information, which would not emphasize amplitude in the same way. Thus, the choice of the 'A' display aligns perfectly with the requirement of showing amplitude over range.
