clutterRegionData

Create data structure used as input to clutter region plotter

Description

example

plotterData = clutterRegionData(cluttergen) creates a plotter data structure plotterData from a ClutterGenerator object cluttergen. The data structure is used as input to the plotClutterRegion function.

data = clutterRegionData(cluttergen,plotheight) also specifies the height plotheight of the clutter region.

Examples

collapse all

Create a radar scenario with a radarDataGenerator object attached to a platform.

scenario = radarScenario;
rdr = radarDataGenerator(1,'no scanning', ...
    'FieldOfView',[30 30],'MountingAngles',[0 45 0]);
platform(scenario,'Sensors',rdr,'Position',[0 0 1e3]);

Enable clutter generation using the clutterGenerator.

clut = clutterGenerator(scenario,rdr);

Run the scenario for one frame.

dets = detect(scenario);

Create a theater plotter with an associated clutterRegionPlotter. Then plot the default clutter region.

tp = theaterPlot;
regPlotter = clutterRegionPlotter(tp, ...
    "DisplayName","Radar beam footprint");
regPlotterData = clutterRegionData(clut);
plotClutterRegion(regPlotter,regPlotterData)

Figure contains an axes object. The axes object contains an object of type patch. This object represents Radar beam footprint.

Input Arguments

collapse all

Clutter generator, specified as a ClutterGenerator object.

Height for all regions, specified as a scalar. Units are in meters.

Output Arguments

collapse all

Plotter data structure, returned as a struct.

Field NameDescription
Xx-coordinates of region specified as a M-by-N matrix. Each column contains the x-coordinates of a different clutter region. N is the number of clutter regions.
Yy-coordinates of region specified as a M-by-N matrix. Each column contains the y-coordinates of a different clutter region. N is the number of clutter regions.
RegionPlotHeightHeight of the clutter region, specified as a scalar. The same height applies to all regions.
PatchCentersPatch centers, specified as a 3-by-N matrix where each column is a patch center position in scenario coordinates.

The units for all fields of the struct are in meters. The RegionPlotHeight field is obtained from the plotheight input argument.
