' 5 If I(|rl) is monotonically decreasing in the interval 0 < I r+I < D and zero outside the interval it is bounded by the function I(0) rect (Ir+l). Hence, the magnitude of the Fourier transform decreases more rapidly than Ifland Eq. (19) provides an estimate of its width [because I(If 1) = sinfD/f for the rect function]. The assumption of a quasi-homogeneous source imposes continuity requirements on the source distribution which are not satisfied by the rect function viz., [I(r)]' 1 2 [I(r')]/2 I(r+). Therefore, the rect function provides a physical and mathematical upper bound for distributions of interest. 1A. M.. Yaglom, Stationary Random Functions, (Prentice Hall, London, 1962), pp. 84-85. 1L.
