In contrast with CWR-BUCKLE program, which use probability density functions, the probabilistic computational algorithm of SCFJ program is based on the evaluation of convolution integrals (Ghiocel & Lungu, 1975) in a discrete approach (Ghiocel & Lungu, 1982), using the histograms of the main parameters which characterize the stability of the CWR track (Ungureanu & Dosa, 2007).

A state-space description of a LTI-TDS can be provided by the set of FDEs in the form (1) where x [member of][[??].sup.n] is a vector of state variables, u [member of] [[??].sup.m] stands for a vector of inputs, y [member of] [[??].sup.l] represents a vector of outputs, [A.sub.i], A([tau]), [B.sub.i], B([tau]), C, [H.sub.i] are real matrices of compatible dimensions, sums with 0 [less than or equal to] [[eta].sub.i] [less than or equal to] L stand for lumped (point-wise) delays and convolution integrals express distributed delays.
We will restrict our attention to convolution integrals throughout the remainder of this paper.
Later, the often ray-tube integration called approach was employed for 2D ISAR image generation  and it was even recognized that the resulting convolution integrals can be efficiently evaluated by Fast Fourier Transform (FFT) based fast convolutions .
