2. Radar chart - Wikipedia

   en.wikipedia.org/wiki/Radar_chart

   The radar chart is a chart and/or plot that consists of a sequence of equi-angular spokes, called radii, with each spoke representing one of the variables. The data length of a spoke is proportional to the magnitude of the variable for the data point relative to the maximum magnitude of the variable across all data points.

3. Tornado diagram - Wikipedia

   Completed Tornado Diagram. Tornado diagrams, also called tornado plots, tornado charts or butterfly charts, are a special type of Bar chart, where the data categories are listed vertically instead of the standard horizontal presentation, and the categories are ordered so that the largest bar appears at the top of the chart, the second largest appears second from the top, and so on.

4. Plan position indicator - Wikipedia

   en.wikipedia.org/wiki/Plan_position_indicator

   A plan position indicator (PPI) is a type of radar display that represents the radar antenna in the center of the display, with the distance from it 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 ...

6. Radiation pattern - Wikipedia

   en.wikipedia.org/wiki/Radiation_pattern

   Side lobe levels of −20 dB or greater are usually not desirable in many applications. Attainment of a side lobe level smaller than −30 dB usually requires very careful design and construction. In most radar systems, for example, low side lobe ratios are very important to minimize false target indications through the side lobes.

7. Mini-automatic radar plotting aid - Wikipedia

   en.wikipedia.org/wiki/Mini-automatic_radar...

   Mini-automatic radar plotting aid (or MARPA) is a maritime radar feature for target tracking and collision avoidance. Targets must be manually selected, but are then tracked automatically, including range, bearing, target speed, target direction (course), CPA (closest point of approach), and TCPA (time of closest point of approach), safe or dangerous indication, and proximity alarm.

8. Sensitivity time control - Wikipedia

   en.wikipedia.org/wiki/Sensitivity_Time_Control

   It is represented in terms of numerical value typically expressed in decibels (dB), starting from zero, indicating that there is no muting and that the radar system is accepting all returns. The radar equation is based on 1 / r a n g e 4 {\displaystyle 1/range^{4}} , meaning that doubling the range to a target results in sixteen times less ...
