Since the intermittent sampling is done in the fast time, false point scatterers will be introduced only in the down-range where each point spread function (PSF) is a scaled sinc function.

The first bracketed quantity in the above equation can be assumed to be constant for the purpose of comparing solid, liquid and gaseous scatterers. Now for the purpose of medical imaging, it can be assumed that the compressibility of a solid particle is much less than that of the surrounding medium, whereas, the density of the particle is greater.
Let us consider the scatterer as a second-order nonlinear system (S) excited with x(t), and where the response [y.sub.NL](t) is given by [y.sub.NL](t) = NL[x(t)] = [N.sub.1]x(t) + [N.sub.2][x.sup.2](t), where [N.sub.1] and [N.sub.2] are respectively linear and second-order coefficients.
The monotonous character of the rise is due to the configuration averaging process that makes [??][C.sub.s][??] and [??]S[??] intrinsic properties of the system that do not depend on the relative positions between the scatterers but rather on an average distance, which is only function of the filling fraction.

where F([DELTA]z, [V.sub.hor]) is the neutron flux through the slit, [alpha] is the coefficient responsible for a finite scatterer efficiency and for the approximations used in the model, [[beta].sub.n] is a population of nth quantum state, [V.sub.hor] is a neutron horizontal velocity component, and L is the mirror length along the neutron beam axis.
For the calculation of the considered mechanical system the real constructive parameters of the investigated seeding opener with the oscillating scatterer of the grainfertilizer seeder have been used.
In the last few decades, estimating the locations of point-like scatterers in open space have caught enormous attention.
J,(r) = Xr)E\ot (r), here note that the contrast function of scatterer is [chi](r) = [[epsilon].sub.r](r)/[[epsilon].sub.0] - 1 and the total electric field is [E.sup.tot.sub.i](r) = [E.sup.inc.sub.i](r) + [E.sup.sca.sub.i](r) for r [member of] D .
To be more precise, we also introduce an additional disorder mechanism, random substitutions of scatterer potentials, as described below.
where [[sigma].sub.l]([x.sub.l], [y.sub.l]) and ([x.sub.l], [y.sub.l]) are the complex reflection coefficient and position of the l-th scatterer, respectively; c is the light velocity; [R.sub.l]([x'.sub.m], [y'.sub.n]) is the path delay from the transceiver at ([x'.sub.m], [y'.sub.n]) to the l-th scatterer and is of the form as
