plotReflectivityMap

Plots reflectivity map

Since R2024a

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.

Plot Reflectivity Map for Land Surface

Open Live Script

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
