FIGURE 2.8 Experimental power distributions obtained from targets at differing ranges.
(a) Experimental estimation of a noisy signal distribution. The distribution is obtained

from a target (a RADAR corner reflector of RCS 10 m ) at 10.25 m. (b) Experimental
estimation of a noisy signal distribution obtained from a wall at approximately 150 m.
