                     As has been seen, the RCS of a complex target varies with both transmitted

               frequency  and  aspect  angle.  Another  important  characteristic  of  a  target’s
               signature is the decorrelation interval in time, frequency, and angle. This is the
               change  in  time,  frequency,  or  angle  required  to  cause  the  echo  amplitude  to
