How to plot heatmaps inside a table?

I want to plot a figure like the following picture, but I don't know how to deal with the grouped row headings. Any hint will be appreciated!

Maybe just have different axis for each radar. There are a few ways, but tiledlayout is easiest:
heatvals = rand(4,40); % random data for 1 radar
% labels with prefix
y_labels = split(num2str(1:4));
y_labels = strcat('Target',{' '}, y_labels);
% tiledlayout with tight spacing
tlo = tiledlayout(2,1,'TileSpacing','tight');
% using imagesc to show colormaped data
h(1)=nexttile(tlo);
imagesc(heatvals)
yticklabels(y_labels)
xticklabels([]); % hide xlabels here
ylabel('Radar1')
h(2)=nexttile(tlo); % for radar2
imagesc(heatvals);
yticklabels(y_labels)
ylabel('Radar2')
% same colormap for the tiles
cb = colorbar;
set(h, 'Colormap', flipud(hot), 'CLim', [0 1])
cb.Layout.Tile = 'east';

Thanks for your nice answer! But when I run your code, I get "Error setting property 'TileSpacing' of class 'TiledChartLayout':
'tight' is not a valid value.". Is this the problem of my matlab version? I'm using R2019b.
yes it looks like tight is not an option in R2019b, maybe you can try 'none' or 'compact'
in this case 'none' is similar to 'tight' since it doesn't have xtickslabels
