The short answer is that they are three different ways of sensing the world.</p> <ul> <li><strong>Radar</strong> sends out radio energy and measures the echo that comes back.</li> <li><strong>RF detection</strong> listens for radio transmissions already present in the air.</li> <li><strong>EO surveillance</strong> uses visible or infrared imaging to look at the scene directly.</li> </ul> <p>They can all be used in security and low-altitude awareness, but they do not see the same thing and should not be treated as interchangeable.</p>
