雷达定义的IEEE标准：“雷达显示器”种类 留言

A display in which targets appear as vertical deflections from a horizontal line representing a time base. Time delay, or target range is indicated by the horizontal position of the deflection from one end of the time base. The vertical deflection is a function of signal amplitude.

A rectangular display in which each target appears as an intensity-modulated blip, with azimuth indicated by the horizontal coordinate and range by the vertical coordinate.

A rectangular display in which each target appears as an intensity-modulated blip with azimuth indicated by the horizontal coordinate and angle of elevation by the vertical coordinate.

A rectangular display in which targets appear as intensity-modulated blips with range indicated by the horizontal coordinate and elevation angle by the vertical coordinate. The term “E-display” has also been applied to a display in which height or altitude is the vertical coordinate; however, this usage is deprecated because of ambiguity. The preferred term for such a display is range-height indication(RHI).

A rectangular display in which a target appears as a centralized blip when the radar antenna is aimed at it. Horizontal and vertical aiming errors are respectively indicated by horizontal and vertical displacement of the blip.

A modified A-display in which the time base is a circle and targets appear as radial deflections from the time base.

A display in which target echoes (blips)are shown in plan position, thus forming a map-like display, with radial distance from the center representing range and with the angle of the radius vector representing azimuth angle.

A display featuring vertical PPI-type display slices superimposed on a single display to show the variation in detection intensity as a function of height. Intensity and height slice detection are normally shown in color or shades of gray.

An intensity-modulated display in which horizontal and vertical distances of a blip from an origin in the lower-left part of the display represent target ground range and target height, respectively. 

The display is generated by successive range weeps starting at the origin and inclined at an angle that varies progressively in accordance with the elevation scan of the radar antenna at a selected azimuth. The height scale of the display is usually expanded relative to the range scale.

在之前的标准中，还有D/G/H/I/K/L/M/N/O/R-display等类型，感兴趣的可自行查看。给雷达通信电子战公众号回复关键词“181221”可下载 IEEE Std 686-2017。

雷达图像可插入各种标志信号，如距离标志、角度标志和选通波门等，甚至可插入或投影叠加地图背景，作为辅助观测手段。为了录取目标信号或选择数据，雷达图像上可插入数字式数据、标记或符号。雷达显示器还能综合显示其他雷达站或信息源来的情报并加注其他状态和指挥命令等，作为指挥控制显示。
