WebPROBLEM. In Section 2.2.5 of the text, it was demonstrated that the radar cross section (RCS) of a target modeled as a set of “many” individual point scatterers was a sufficiently complex function of aspect angle (or frequency) that it could be modeled as a random variable; and further that the law of large numbers suggests that one assume an … WebSmith, J.
