Radar Class
Represents a single Radar as part of a RadarVideoLayer.
NuGet/Assembly: Carmenta.Engine.5.16.2.nupkg (in the CECore assembly)
Syntax
public class Radar : EngineObjectRemarks
A Radar represents the position and area of a radar intensity image and is visualized with a RadarVideoLayer. The intensity image is mapped such that the rows in the image represents the rays at different angles and the columns represents distance from the Position. The size of the intensity image is defined by the Rows and Columns properties. The intensity image is colored with the Color property. This property may be set to either a constant color value or a color palette defined by KeyedAttributeVariable<System.Drawing.Color>. A constant color value will assume intensity in the range [0,1] while a palette will use the range defined by the keys.
The orientation of the radar intensity image is defined by the MaxRange, MinRange, SweepAngle and Direction properties according to the image below.
 |
The intensity image's first row represent the ray directed towards direction - sweepAngle/2 and the last row represents the ray directed towards direction + sweepAngle/2. All angles are in degrees. The first column is located closest to the radar.
It is not possible to alter the maximum or minimum range or change the number of rows or columns after a radar is created. This requires a new radar instance.
The image data is set using the UpdateRows method that lets the user update any number of rows at once. The data is an array of doubles that are clamped to the range [0, 1] if a constant color value is used, otherwise the range of the keys in the color table is used.
The position of the radar is given in Wgs84 longitude and latitude coordinates.
