    Syntax

    plotReflectivityMap(surface)
    plotReflectivityMap(surface,Parent=HAX)
    HAX = plotReflectivityMap(___)

    Description

    plotReflectivityMap(surface) plots the reflectivity map indices relative to the size and domain of the surface, where surface is a LandSurface or SeaSurface.

    example

    plotReflectivityMap(surface,Parent=HAX) specifies the plot axes, HAX, for the reflectivity plot of the surface, where surface is a LandSurface or SeaSurface.

    HAX = plotReflectivityMap(___) returns the handle to the axes in the figure.

    This example shows how to plot the reflectivity map for a land surface composed of woods and rolling hills.

    Create Land Surface and Plot

    Create a land surface composed of two different materials and plot the reflectivity map.

    % Create a scenario
scene = radarScenario;   
  
% Specify custom reflectivity table with two surface types
load("heightMap.mat")
bnds        = [-50 50; -50 50];
grazTable   = 20:0.1:60;
freqTable   = [1e9 10e9];
numSurfaces = 2;
reflTypes   = zeros(numel(grazTable),numel(freqTable), ...
    numSurfaces);
reflTypes(:,:,1) = landreflectivity("Woods", ...
    grazTable,freqTable);
reflTypes(:,:,2) = landreflectivity("RollingHills", ...
    grazTable,freqTable);
reflMap           = ones(size(hmap));
reflMap(hmap > 4) = 2;
refl = surfaceReflectivity("Custom", ...
    Frequency=freqTable, ...
    GrazingAngle=grazTable,Reflectivity=reflTypes);
    
% Create land surface
srf = landSurface(scene,Terrain=hmap,Boundary=bnds, ...
    RadarReflectivity=refl,ReflectivityMap=reflMap);
    
% Plot reflectivity map
plotReflectivityMap(srf)

    Figure contains an axes object. The axes object with title Reflectivity Map, xlabel X (m), ylabel Y (m) contains 2 objects of type surface, line. One or more of the lines displays its values using only markers

    Input Arguments

    collapse all

    Surface, specified as a LandSurface object created by landSurface or SeaSurface object created by seaSurface.

    Handle to plot axes, specified as an Axes object. Use the gca function to get and set properties of the current axes.

    Output Arguments

    collapse all

    Handle to the axes displayed in the figure, returned as an Axes object.
