✦ Synopsis

The two incident field directions are ki, and k;,. Displacement of p and ij' by A x gives ($T( p + z3(cl,*( P' + L)) = / d ~" / d ~' " ( G ( ij + n, F")G*( ij' + .hx, p"'))

x Ji,( P').Q( ij?

The last equality is a result of the fact that the antenna Jil creates incident wave ki, and the antenna Ji2 creates incident wave k,. Also Thus, substituting (A.9) into (A.8) and using (A.7)

sin Oilsin ei2 = sin e,, -sin Os2.

No matter how the buried object is made to imitate the clutter, it is a single scattering object and does not have statistical translational invariance. Thus the buried object does not have the generalized phase matching condition of clutter and will not exhibit memory effects as clutter does.
