Abstract :
It is proved in this paper that for an arbitrary target at arbitrary aspect-angle the three average radar cross sections (RCS) for polarization matched radar, for common antenna radar, and for cross polarization radar, satisfy a simple proportional relation, i.e., 3:2:1. Here the average is the probability average, assuming that the radar transmitting polarization runs on the Poincare sphere with uniformly distributed probability density function
