Quantum Radar Cross Section
So far our discussion on quantum radar has ignored the geometry and composition of the target. In practice, of course, targets will present intricate geometries that will reflect the incoming photons on a complex pattern. Within the realm of classical radar theory, the radar cross section σC is used to determine the “radar visibility” of a specific target.
We recall from Chapter 4 that σC is defined as the ratio between the power reflected back to the receiver per unit solid angle and the incident power density. As we discussed, σC emerges as a critical concept in classical radar theory, as it offers an objective measure of performance for the radar system and the stealth capabilities of modern weapon platforms. ...
