How Object detection?

Hello. I have an object named Tank. I want to detect the object. What toolbox can be used for tank detection in matlab? Or what code can be used?

Do you see any practical problems with this example?

if istank(object)
    disp('tank detected')
end

Vague or abstract questions really aren't answerable with anything but vague or abstract answers. What is the "object"? In what sense do you "have" it without "detecting" it? Is this simulated or applied? Image processing? Other sensor data?

@DGM I have a picture. The object in that picture is a tank. I want to identification the tank in that picture. While researching in Matlab, I found a similar example Automatic Target Recognition (ATR) in SAR. But that example didn't work in Matlab 2019Rb. Do you know other similar examples?
