Radar cross section definition

The definition of the radar cross section (RCS) is illustrated in Fig. 2.5. Here a fictitious flat plate, with area a ant, intercepts an incident plane wave with power density —that is, the intercepted power is dant b,. 

This definition has been known at least since World War II [55] and has been widely quoted eversince [37, 38, 56-58]. What is more, it has often been implied that this class of antenna represents the ultimate as far as low radar cross section is concerned and, consequently, should be treated with great respect ... 

McDonald (1962) has described the definition of the radar backscattering cross section as intrinsically awkward we heartily agree that it is awkward, but we... 

The traditional definition of the radar backscattering cross section can be stated clearly in a few words it is just 4it times what it ought to be. We therefore counsel the reader to mentally delete the factor 4it in (4.82) and only reintroduce it as a sop to convention when necessary.
