Abstract

The radar cross section σ_C is an objective measure of the "radar visibility" of an object. As such, σ_C is an important concept for the correct characterization of the operational performance of radar systems. Furthermore, σ_C is equally essential for the design and development of stealth weapon systems and platforms. Recent years have seen the theoretical development of quantum radars, that is, radars that operate with a small number of photons. In this regime, the radar-target interaction is described through photon-atom scattering processes governed by the laws of quantum electrodynamics. As such, it is theoretically inconsistent to use the same σ_C to characterize the performance of a quantum radar. In this paper we define a quantum radar cross section σ_Q based on quantum electrodynamics and interferometric considerations. We discuss the theoretical challenges of defining σ_Q, as well as computer simulations of σ_C and σ_Q for simple targets.
